Missing rules in php5 abstraction

[impact]

This bug prevents the proper functioning of apache mod_php with
mod_apparmor.

[steps to reproduce]

1) setuo apache and mod_php, verify php scripts are working
2) stop apache2
3) install mod_apparmor
4) restart apache2
5) with fix applied, apache should not generate rejections for /tmp/.ZendSem.*
for php scripts confined by mod_apparmor

[regression potential]

The change to the php abstraction in the patch for this bug is a
slight loosening of the apparmor policy. The risk of an introduced
regression is small.

[original description]

I am using apache mod_apparmor with a wordpress blog. In my rules I have:
#include <abstractions/php5>

But this did not allow all access that was needed:
apparmor="DENIED" operation="file_lock" profile="/usr/sbin/apache2//myvhost.example.com" name="/tmp/.ZendSem.Y5Ghmr" pid=21874 comm="apache2" requested_mask="k" denied_mask="k" fsuid=33 ouid=0
apparmor="DENIED" operation="file_lock" profile="/usr/sbin/apache2//myvhost.example.com" name="/tmp/.ZendSem.Y5Ghmr" pid=21874 comm="apache2" requested_mask="wk" denied_mask="wk" fsuid=33 ouid=0

This access seems to be needed by opcache module, I found some info about it here:
