test failures during rpmbuild

[Antoine Martin]

Tests were re-enabled in r23918 because the tests pass when run from the command line, even from a clean user account logged in via su.
But they still fail during rpmbuild:

running unit.server.server_sockets_test

xpra initialization error:

A stray server from the previous failed test?

removing the python2 tests "fixes" things, so something must be left over from those tests.
Just to get moving again, r24039 removes those tests again.

Another issue seems to be some spinning xpra_signal_listener processes left behind.
Doesn't occur with v4.0, odd.
