mdocml: In man(1) mode, prefer file name matches over .Dt name matches

[schwarze]

Log Message:
-----------
In man(1) mode, prefer file name matches over .Dt name matches over
first .Nm entries over other NAME .Nm entries over SYNOPSIS .Nm entries.
For example, this makes sure "man ypbind" does not return yp(8).
Re-run "makewhatis" to profit from this change.
