Fix HAVE_INTROSPECTION does not appear in AM_CONDITIONAL

​

During autoreconf GOBJECT_INTROSPECTION_CHECK could not be resolved because we

don't have introspection which provides its custom m4 macro. Reconfigure fails

with:

​

gdk/Makefile.am:196: error: HAVE_INTROSPECTION does not appear in AM_CONDITIONAL

gtk/Makefile.am:1347: error: HAVE_INTROSPECTION does not appear in AM_CONDITIONAL

​

We avoid to add a copy of introspection.m4 in the m4 directory of libgtk3 by

adding a check, as performed in Systemd.
