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
