[PATCH v2] combo-layer: handle file_exclude matching dirs

[Olaf Mandel <o.mandel@menlosystems.com>]

If file_exclude matches a directory, os.unlink() got called with this
directory as an argument.

Filter out paths that end in a directory separator.

This still leaves the (then empty) directories, but this does not affect
the git commit.
