tests: Invoke ps in a way that does not truncate wide output.
By default, 'ps' truncates its output to about 100 characters. The test-termination test depends on finding the socket file name in the output of the 'ps' command; it could fail depending on the file name length of the directory where the test was run.
- tests/test-termination.c (get_daemon_pid) : Invoke with the -ww option to preserve all the output.
