[apparmor] [Patch] [2.8] Fix caching failure due to features cache being larger than read buffer

[John Johansen]

This is a minimal fix to apparmor 2.8 for cache failures when the feature
file is larger than the feature buffer used for cache version comparison.

Ideally this would be dynamically allocated but for 2.8 just bumping the
buffer size is the quick fix.
