If kernel_do_compile() encounters a .lzma image for the initramfs, it
attempts to decompress it using the little-known "lzmash" utility.  This
may not be present, which will cause the build to fail.

Fortunately, it appears that the more mainstream "lzma" tool is
compatible so we can use that one instead.
