mdocml: Give manuals in purely numerical sections priority over manuals

[schwarze@mdocml.bsd.lv]

Log Message:
-----------
Give manuals in purely numerical sections priority over manuals of 
the same name in sections with an alphabetical suffix (on OpenBSD,
mostly 3p), restoring behaviour of the traditional BSD man(1) that
got lost in the switch to the mandoc-based implementation.

Issue reported by jsg@, using an idea by mikeb@ for the solution,
and at least afresh1@ and jasper@ also seem in favour of the direction.
