[apparmor] [patch] aa-genprof: fix last_audit_entry_time()

[Christian Boltz]

Hello,

last_audit_entry_time() was waiting forever because 
subprocess.check_output() started tail without any parameters.
Fixed by removing shell=True (default is shell=False).

Also fix the regex ("^.*", the dot was missing).

Needless to say - I verified that logmark really contains the timestamp
from audit.log.
