[OE-core][PATCH] lib: license_finder: Ignore non-files in license directories

[Joshua Watt]

We would like to move the SPDX license exception files to a
subdirectory, but that breaks the license finder code since it assumes
everything in the license directory is a file and fails when it is a
directory.
