bzip2/lzma: fix built-in initramfs vs CONFIG_RD_GZIP
Impact: Resolves build failures in some configurations
Makes it possible to disable CONFIG_RD_GZIP . In that case, the
built-in initramfs will be compressed by whatever compressor is
available (bzip2 or lzma) or left uncompressed if none is available.
It also removes a couple of warnings which occur when no ramdisk
compression at all is chosen.
It also restores the select ZLIB_INFLATE in drivers/block/Kconfig
which somehow came missing. This is needed to activate compilation of
the stuff in zlib_deflate.
