profiles: rename disable-X11.inc to disable-x11.inc (#6294)

That is, make "X11" lowercase so that the order of the includes in the
disable- section remain the same when sorted with `LC_ALL=C`, as is the
case for most of the other sections.  That is also likely to be the
default in text editors (such as in vim on Arch), so this should make
the disable- section more consistent and easier to sort when editing the
profile.

Also, keep the old include as a redirect to the new one for now to avoid
breakage.

Commands used to search and replace:

    git mv etc/inc/disable-X11.inc etc/inc/disable-x11.inc
    git grep -Ilz 'disable-X11' -- etc | xargs -0 \
      perl -pi -e 's/disable-X11/disable-x11/'

Relates to #4462 #4854 #6070 #6289.

This is a follow-up to #6286.
