John Johansen e2d55844a2 parser: fix integer overflow bug in rule priority comparisons 
There is an integer overflow when comparing priorities when cmp is
used because it uses subtraction to find lessthan, equal, and greater
than in one operation.

But INT_MAX and INT_MIN are being used by priorities and this results
in INT_MAX - INT_MIN and INT_MIN - INT_MAX which are both overflows
causing an incorrect comparison result and selection of the wrong
rule permission.

Closes: https://gitlab.com/apparmor/apparmor/-/issues/452
Fixes: e3fca60d1 ("parser: add the ability to specify a priority prefix to rules")

README 

The apparmor_parser allows you to add, replace, and remove AppArmor
policy through the use of command line options. The default is to add.
`apparmor_parser --help` shows what the command line options are.
