Make it possible to compile mkfs.ubifs without zlib
This one is a bit trickier than adding WITH_ZLIB ifdefs. Some parts
of the code assume that zlib is always present and have complicated
fallback behavior. Particularly the "favor_lzo" compression method
that uses either zlib or lzo, whichever produces the better result.
