sway: request SCHED_RR via RTKit

Browse source 
This tries to connect to DBUS to request RTTimeUSecMax from RTKit and
than changes the scheduling policy of sway to SCHED_RR. I tested the
impact using hackbench, with this patch I don't see any cursor
stuttering while running the following hackbench command:

  $ hackbench -f 100 -l 100000 -s 100000

This also fixes the "your compositor is too slow"-warnings from
libinput.

The rtkit feature is currently auto, so if one of the SD-Bus libraries
is installed we will select it. However we will fail graciously with
only a debug note if we can't reach RTKit and won't touch RLIMIT_RTTIME
in this case. Users who don't want to have DBUS within sway itself can
disable the feature.
