[apparmor] [PATCH 1/2] Use mtime instead of ctime for cache file

[John Johansen]

For cache file. For some inexplicable reason when we converted the
cache to use mtime, the timestamp used from the cache file never
got switched from ctime to mtime.

The means we are comparing the cache files ctime against the policy
files mtime. Which can make the cache look newer than it really
is.
