gnome-base/gdm: add elogind support

Include a patch from 3.32 that removes long gone legacy argument
to pam_systemd.so, as to make it uniform with the added elogind
support (and not add that legacy arg there too) and be able to
reuse the pam-elogind.patch bits for 3.32 without changes, just
dropping the argument patch.

The elogind support is achieved without configure.ac patches by
making use of the standard PKG_CHECK_MODULES builtin AC_ARG_VAR
provided variable override support and passing elogind values
there as a drop-in replacement. So we don't need an eautoreconf
and maintaing an autotools patch until upstream moves to meson.

Initial VT is put back to 7 for elogind for the time being until
there is more clarity what will happen with startDM.sh and how
things interact with agetty out of the box (potential keyboard
stealing, etc).
