It is common for packaged PHP applications to ship a PHP-FPM
configuration using a scheme of "$app.sock" or or "$app.socket" instead
of using a generic FPM socket.

ArchLinux ships a secondary PHP package called php-legacy with different
paths. As of now, the php-fpm profile will cover this binary but
inadequately restrict it.
Fixes: #454
Bash will try to read the passwd database to find the shell of a user if
$SHELL is not set. This causes zgrep to trigger
```
apparmor="DENIED" operation="open" class="file" profile="zgrep" name="/etc/nsswitch.conf" comm="zgrep" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
apparmor="DENIED" operation="open" class="file" profile="zgrep" name="/etc/passwd" comm="zgrep" requested_mask="r" denied_mask="r" fsuid=0 ouid=0
```
if called in a sanitized environment. As the functionality of zgrep is
not impacted by a limited Bash environment, add deny rules to avoid the
potentially misleading AVC messages.

Seen on various VMs, my guess is that bash wants to translate a uid to a
username.

This is unnecessary, users can just directly edit tunables/rygel if they wish to
customise the allowed paths.

gst-plugin-scanner wants to try and scan hardware devices but since rygel itself
doesn't actually use or need any access to such devices the access to these can
be denied and any log spam silenced via an explicit denial rule.

Allow more easy customisation of the paths allowed to rygel by introducing a
tunable which provides the @{rygel_media_dirs} variable and an example
site-local file to show how this can be easily extended. Essentially this
follows the same logic as the home tunable with @{HOME}.
