bzip2/lzma: make internal initramfs compression configurable
Impact: Avoids silent environment dependency
Make builtin initramfs compression an explicit configurable. The
previous version would pick a compression based on the binaries which
were installed on the system, which could lead to unexpected results.
It is now explicitly configured, and not having the appropriate
binaries installed on the build host is simply an error.
