build: Switch from GNOME_CODE_COVERAGE to AX_CODE_COVERAGE
AX_CODE_COVERAGE comes from the autoconf-archive, and is an upstreamed
version of the original GNOME_CODE_COVERAGE macro.
https://savannah.gnu.org/patch/?8451
By switching to it, we reduce our dependency on gnome-common. The master
plan is for gnome-common to simply cease to exist.
See: https://bugzilla.gnome.org/show_bug.cgi?id=729405
