libinput: less parallism to increase chances the test suite works
Discussion with the libinput maintainer has confirmed that many of the
libinput test cases need to run on a relatively unloaded system,
because input handling is by definition time-sensitive and any
event mismatches are considered a failure to avoid broken code hiding.
We can't expect libinput to run on an otherside unloaded machine
because the autobuilder ptests execute in a qemu at the same time
as builds can be happening. We can however reduce the amount of
parallellism happening in the libinput test suite to give it a better
chance of succeeding.
This may not be enough, but it's worth a go.
