            Fix compatibility with Python 3.15

Python 3.15 changed importlib.metadata to raise MetadataNotFound
(a FileNotFoundError subclass) when a distribution has no metadata
file, instead of returning None. This breaks plaster's loader
discovery which iterates all distributions unconditionally.
