Subject: [PATCH] python/sepolicy: Cache conditional rule queries

Commit 7506771e4b630fe0ab853f96574e039055cb72eb
"add missing booleans to man pages" dramatically slowed down
"sepolicy manpage -a" by removing caching of setools rule query.
Re-add said caching and update the query to only return conditional
rules.

Before commit 7506771e:
 #time sepolicy manpage -a
 real	1m43.153s
 # time sepolicy manpage -d httpd_t
 real	0m4.493s

After commit 7506771e:
 #time sepolicy manpage -a
 real   1h56m43.153s
 # time sepolicy manpage -d httpd_t
 real	0m8.352s

After this commit:
 #time sepolicy manpage -a
 real	1m41.074s
 # time sepolicy manpage -d httpd_t
 real	0m7.358s
