gio: Build the portal code only on *NIX

xdg-desktop-portal support is only usable on *NIX platforms, so don't build
them on non-*NIX platforms.  Also clean up gio/Makefile.am a bit to split out
the listings for the platform-specific sources from the platform-neutral
sources, and assemble them for the final list of sources required for libgio.
