Fix incorrect maintainer email address in DOAP file; remove MAINTAINERS file
I got a bounce for <bberg@gnome.org>
in https://gitlab.gnome.org/GNOME/gnome-session/-/blob/master/gnome-session.doap
<bberg@gnome.org>: can't create user output file. Command output: procmail:
Couldn't create "/var/spool/mail/bberg"
Also probably remove MAINTAINERS (duplication).
Heads-up to @bberg.
