treewide: remove unnecessary cache.h includes in source files

We had several C files include cache.h unnecessarily.  Replace those
with an include of "git-compat-util.h" instead.  Much like the previous
commit, these have all been verified via both ensuring that
    gcc -E $SOURCE_FILE | grep '"cache.h"'
found no hits and that
    make DEVELOPER=1 ${OBJECT_FILE_FOR_SOURCE_FILE}
successfully compiles without warnings.
