Update gvfs to 1.6.7.

pkgsrc changes:
* set LICENSE as gnu-lgpl-v2 from COPYING.
* drop -DG_DISABLE_DEPREATED in whole build instead of just in a directory
  by patch-ah, because much deprecated warnings will be appeared with recent
  glib2.
* fix specify to configure of samba location.

Major changes in 1.6.7
======================
This is a convenient release for people who want to have old
gnome 2.32 and new glib:
* Do not build app lookup extension if we have glib >= 2.27.1

Other fixes:
* build: Adapt autogen.sh to libtool-2.4
* build: Bump fuse requirement for ATOMIC_O_TRUNC support
