No need to configure gobject-introspection

It wasn’t needed for the recently-installed xwidget_mvp code; see:
http://lists.gnu.org/archive/html/emacs-devel/2016-01/msg01154.html
* configure.ac (DOES_XWIDGETS_USE_GIR, GIR_REQUIRED, GIR_MODULES):
(HAVE_GIR):
* src/Makefile.in (GIR_LIBS, GIR_CFLAGS):
Remove.  All uses removed.
* configure.ac (emacs_config_features): Don’t worry about GIR.
