glib-2.0: upgrade to 2.32.1

glib-2.0: upgrade to 2.32.1

* g_once_init_enter.patch shouldn't be needed after upstream commit
  794c1a30bc27b4c8d77537813acb1213d5ac80f2

* LIC_FILES_CHKSUM change is only because PCRE was upgraded and now
  pcre.h says "Copyright (c) 1997-2012 University of Cambridge" instead
  of 2010 and COPYING file
  "Please see the file LICENCE in the PCRE distribution for licensing
  details."  but LICENSE file is not part of glib distribution (but still
  BSD in standalone PCRE)
