oomd: don't get pressure candidates on every interval

Only start collecting candidates for a memory pressure kill when we're
hitting the limit (but before the duration hitting that limit is
exceeded). This brings CPU util from ~1% to 0.3%.

Addresses CPU util from
https://bugzilla.redhat.com/show_bug.cgi?id=1941340
and
https://bugzilla.redhat.com/show_bug.cgi?id=1944646

(cherry picked from commit cb13961ada52c1b27f6d6c2c6e37a2901f01ed30)
