[apparmor] [patch 13/18] parser: add rttime rlimit support

[Steve Beattie]

This patch adds support for the rttime rlimit (aka RLIMIT_RTTIME),
available since the 2.6.25 kernel, according to the getrlimit(2)
man page; see that man page for more details on this rlimit.
An acceptance test is also added.
