Nginx + PHP-FPM: Permissions on UNIX socket

Wow thanks Sergey!
That did the trick.

I didn't know that you could add a group as 'supplementary' when it was
already your 'primary' one... Kind of strange trick to do!
I am definitely not familiar with the way permissions are defined for nux
users. ;o)

It's strange that supplementary groups are handled correctly and that Nginx
makes the assumption that the primary group has the same name as the user
when it is not specified in the configuration.
Maxim noted my request as an 'enhancement'. Since the logic is blurry I
would suggest to get back to 'bug'! :oP
