tests: remove pid file by default

Previously, killdaemons.py would kill PIDs listed in a file then
leave the file lingering around.

If the PIDs are killed, then there's no point leaving the PID file
around. In the worst case, a later invocation of killdaemons.py
(run-tests.py invokes killdaemons.py after running a test) could kill
a separate process whose PID conflicted with a previously-killed
process. By removing the PID file, we eliminate this possibility.

Some tests were manually removing the PID file after calling
killdaemons.py. So we update these tests to not do this.

# Dummy extension that adds a delay after acquiring a lock.

# This extension can be used to test race conditions between lock acquisition.
