Remove all the 'CC=gcc' hacks for 'g-ir-scanner'.

* gnu/packages/glib.scm (telepathy-glib)[arguments]: Remove.
* gnu/packages/gtk.scm (at-spi2-core, gtk+-2): Remove #:make-flags.
* gnu/packages/gnome.scm (libpeas, librsvg, vala, vte, json-glib,
  libxklavier, libsoup, libsecret, colord, geocode-glib, libgweather):
  Remove #:make-flags or the '(setenv "CC" "gcc")' phase.
