Subject: [PATCH] Tests: Wait for nginx to create pid file

When nginx is started, it returns control before it has created its pid
file. Since this test suite relies on the existence of the pid file,
wait until the pid file exists before returning from nginx_start. Time
out after 2 seconds so that if there is a real problem starting nginx
we don't wait forever.

Fixes #144
