ext2fs.h: Change how we deal with optional incompat features.

Currently EXT2_LIB_FEATURE_INCOMPAT_SUPP is #defined twice once with
EXT2_FEATURE_INCOMPAT_COMPRESSION and once without depending on the
state of ENABLE_COMPRESSION

Change this to use an intermediate symbol so that the definition of
EXT2_LIB_FEATURE_INCOMPAT_SUPP doesn't change as other optional fetures
are added.
