fix test with system php-fpm

[remicollet]

When using system php-fpm, test can fails, this should fix this:

• -n option to not use system php.ini (which can include additional extensions)
• don't change extension_dir (is enough, previous not really required with this change)
• don't log notice, only warning (additional one break expected output, such as "NOTICE: systemd monitor interval set to 10000ms")

I think the logs should remain in output. What's the reason for removing them?

[remicollet]

Because of additional notices in some build (systemd), and the test is about runkit, not about fpm ;)

$ cat tests/runkit_fpm_internal_function_restore.diff
021+ [19-Oct-2015 09:50:22] NOTICE: systemd monitor interval set to 10000ms

This doesn't work on my computer, and without logs I can't find out why.

Sorry... I think this is related to missing space in fopen command.

I also revert log_level, but only check for the "ready to handle connections" and ignore remaining output.

I can squash the commits if you prefer a single clean one.
