cgit.mk: don't rebuild everything if CGIT_VERSION changes
If CGIT_VERSION is in CGIT_CFLAGS then a change in version (for example because you have committed your changes) causes all of the CGit objects to be rebuilt. Avoid this by using EXTRA_CPPFLAGS to add the version for only those files that are affected and make them depend on VERSION. Signed-off-by: John Keeping <john@keeping.me.uk>
