Revert "uitest: make child soffice process die when parent dies"

This reverts commit d35840a2111beafe018851314a624e268e3cde6a, now that
43aef04d77aafb9d055957642e62b559231f3711 "Reliably wait for soffice to
terminate" makes sure that no soffice-related processes are left behind by
UITests.  Using PR_SET_PDEATHSIG had the following drawbacks:

* It defeats debugging if a runaway process is forcefully killed by the test
framework.  (And there are already higher-layer mechanisms in place for the
reliable termination of runaway tinderbox builds, see the commit message of
43aef04d77aafb9d055957642e62b559231f3711 mentioned above.)

* It is brittle in that it can terminate soffice-related processes too early, as
the signal is sent as soon as the parent's thread that spawned the child (and
not the parent process as a whole) terminates.

* It is Linux-only.
