TestSignalTrace can take a bit longer to run on some
ppc64{,le} machines. I was only able to reproduce the
timeout reliably on a POWER8/ppc64le ubuntu 16.04 host.
Bump the timeout to 5 seconds. This should be more than
sufficient for a test which occasionally takes a bit
longer to run on these builders.
Fixes #45773
