gemini: Add copy-kernel utility package
This package just contains a small Gemini-only assembler
bootstrap loop to copy the kernel from the two fragments
(previously zImage at 0x01600000 and initramdisk at 0x00800000)
into one big zImage of up to 8 MB at 0x00400000.
It will be built on demand from the Gemini image Makefile.
