compat: drop inclusion of <git-compat-util.h>

These two header files are included from ordinary source files that
already include <git-compat-util.h> as the first header file as they
should.  There is no need to include the compat-util in these
headers.

"make hdr-check" is not affected, as it is designed to assume that
what <git-compat-util.h> offers is available to everybody without
being included.
