Bug#963059: x11-common: false linebreak in 20x11-common_process-args function has_option

[Andrey Kiselev <andrey.kiselev@gmail.com>]

Package: x11-common
Followup-For: Bug #963059

Dear Maintainer,

The fix coming with the 1:7.7+21 now breaks users resource loading in the 
gdm3 session. gdm3 has its own Xsession script which was not updated to 
reflect the changes introduced in latest x11-common. It looks like this in 
logs:

Oct 15 12:13:29 rose /usr/libexec/gdm-x-session[2516]: /etc/gdm3/Xsession: Beginning session setup...
Oct 15 12:13:29 rose /usr/libexec/gdm-x-session[2516]: /etc/gdm3/Xsession: 16: /etc/X11/Xsession.d/30x11-common_xresources: has_option: not found

There is a possibility that some other session managers can be the same way 
affected.

I think that the quick fix is to move has_option() function back into the
"20x11-common_process-args" file.

Best regards,
Andrey
