t_client.sh: Improve detection if the OpenVPN process did start during tests

This will check the OpenVPN log file if the process initialized
successfully.

It will check the log file for 30 seconds before aborting the test run.
This also has the advantage of starting the testing quicker if the
initialization goes faster than 10 seconds (which was the old sleep time).

The umask is also set to a more permissive mode to ensure the test
script is capable of reading the OpenVPN PID file, as that will be
created by root.
