tools: drop unused upslug2 and wrt350nv2-builder

These tools have been used by the orion target which has been
removed in Jan 2020 [1].

Both were specifically meant for the WRT350Nv2, which is not
supported anymore.

So, let's remove them as well.

-
-	A lot of thanks to Kaloz and juhosg from OpenWRT and Lennert Buytenhek from
-	marvell for helping me figure this one out. This code is based on bash
-	scripts wrote by Peter van Valderen so the real credit should go to him.
-
-	This program reads the provided parameter file and creates an image which can
-	be used to flash a Linksys WRT350N v2 from stock firmware.
-	The trick is to fill unused space in the bin file with random, so that the
-	resulting zip file passes the size check of the stock firmware.
-
-	The parameter file layout for an original Linksys firmware:
-		:kernel	0x001A0000	/path/to/uImage
-		:rootfs	0	/path/to/root.squashfs
-		:u-boot	0	/path/to/u-boot.bin
-		#version	0x2020
-
-	Additionally since v2.4 an already complete image can be used:
-		:image		0	/path/to/openwrt-wrt350nv2-[squashfs|jffs2-64k].img
-
-	args:
-		1	wrt350nv2.par		parameter file describing the image layout
-		2	wrt350nv2.img		output file for linksys style image
-
-	A u-boot image inside the bin file is not necessary.
-	The version is not important.
-	The name of the bin file is not important, but still "wrt350n.bin" is used to
-	keep as close as possible to the stock firmware.
-
-	Linksys assumes that no mtd will be used to its maximum, so the last 16 bytes
-	of the mtd are abused to define the length of the next mtd content (4 bytes for
-	size + 12 pad bytes).
-
-	At the end of "rootfs" additional 16 bytes are abused for some data and a
-	highly important eRcOmM identifier, so the last 32 bytes of "rootfs" are abused.
-
-	At the end of "u-boot" 128 bytes are abused for some data, a checksum and a
-	highly important sErCoMm identifier.
-
-
-	This program uses a special GNU scanf modifier to allocate
-	sufficient memory for a strings with unknown length.
-	See http://www.kernel.org/doc/man-pages/online/pages/man3/scanf.3.html#NOTES
-
-
-	To extract everything from a Linksys style firmware image see
-	https://forum.openwrt.org/viewtopic.php?pid=92928#p92928
-
-	Changelog:
-	v2.4 - added ":image" definition for parameter file, this allows
-	       to use a complete sysupgrade image without any kernel size check
-	v2.3 - allow jffs by adding its magic number (0x8519)
-	       added parameter option -i to ignore unknown magic numbers
-	v2.2 - fixed checksum byte calculation for other versions than 0x2019
-	       fixed rare problem with padsize
-	       updated info to stock firmware 2.00.20
-	       fixed typos
-	v2.1 - used "wrt350n.bin" for the created image (closer to stock)
-		added option to create the image in two separate steps (-b / -z)
-	v2.0 - complete re-write
