ramips: fix image generation for mt76x8
Buildbot fails to generate images for targets also generating a
Sercomm binary with following error:
Opening file: /mnt/ramdisk/koen/firmware/builds/owrt_mt76x8/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/tmp/openwrt-ramips-mt76x8-netgear_r6120-squashfs-factory.img.rootfs.zip
Filesize: 3648606 .
mksercommfw: malloc.c:2427: sysmalloc: Assertion `(old_top == initial_top (av) && old_size == 0) || ((unsigned long) (old_size) >= MINSIZE && prev_inuse (old_top) && ((unsigned long) old_end & (pagesize - 1)) == 0)' failed.
Makefile:287: recipe for target '/mnt/ramdisk/koen/firmware/builds/owrt_mt76x8/build_dir/target-mipsel_24kc_musl/linux-ramips_mt76x8/tmp/openwrt-ramips-mt76x8-netgear_r6120-squashfs-factory.img' failed
Debugging using valgrind shows stack corruption due to a buffer overflow.
The author of the generator assumes the filename ends with "root",
while it should be "rootfs".
Fix this by accounting for the 2 missing characters which solves the build issues.
More work is required to cleanup this source, which will be done later on.
