run_test_suite: Don't try and use XVFB_PID if it's not defined.
Originally created by @lamby on #15730 (Redmine)
We try and use XVFB_PID
in the cleanup, even though it’s not
guaranteed to be defined. This results in an ugly and (moreover)
misleading ./run_test_suite: line 145: XVFB_PID: unbound variable
message.
Patch attached.
