[apparmor] [patch] parser: fix uninitialized field in convert_aaregex_to_pcre() [resend]

[Steve Beattie]

This is an unchanged resend of the patch from this thread:
https://lists.ubuntu.com/archives/apparmor/2015-August/008494.html

The first entry in the grouping_count array is never initialized to 0;
subsequent depths are. This patch fixes the issue.
