[arch-projects] [namcap] [PATCH v2 3/4] nonuniquesources: Also warn on downloaded common filenames not overriding name to be unique

[James P. Harvey]

Downloaded files in source() are required to be unique.  A common
violation of this is from community named files (i.e. LICENSE) that
aren't part of an upstream tarball.

Warn if a source file is downloaded, doesn't have an overriding name,
and has a commonly used name, ignoring extension and case.
