commit 394d7134ec42f14ddb91769c737098753fa68266

tools/bzip2: add `bzip2` binaries
`bzip2` is the standard executable for bzip2 compression
this includes development includes and both static and shared libs
(libbz2) which can be used by other packages
the initramfs generator offers the BZIP2 option but there was no
executable to support it, and worked only via side effect of having a
system-installed version of bzip2, which could be less predictable
