In installman, move the call to File::Find::find() to the top level.

The code to recursively scan a directory with File::File::find() is now only
used by one caller of podset(), so move it to the call point, reducing the
amount of conditional code within podset(). The first argument to podset()
is now always a reference to a hash of "work to be done". Add an optional
fourth argument to give the directory name for diagnostics.
