When makewhatis(8) scans a tree, ignore trailing garbage on filenames.

This is relevant because some ports install files like man1/xsel.1x,
as reported by patrick keshishian <pkeshish at gmail dot com> on misc@.

We can probably improve functionality and simplify the code by ignoring
file name extensions altogether; we already know the section number from
the name of the directory.  But so close to lock, i'm keeping the fix
minimal.
