Fix reloading php-fpm on trusty & utopic
Fix reloading php-fpm on trusty & utopic

Ubuntu versions newer than precise support reload signals but that
feature is disabled by the package maintainer because he builds
packages with the same upstart config for precise, too.

But because we actually use reload, refreshing the service doesn't work
correctly which leads to php-fpm child processes that never get killed.
These processes prevent restarting php-fpm altogether. The only fix is
manually killing them.

See https://bugs.launchpad.net/ubuntu/+source/php5/+bug/1242376 for
reference.

This patch ensures that reloading is not used on precise and the reload
signal USR2 is used for all other supported versions of Ubuntu by
creating an upstart override file.
