[pacman-dev] [PATCH 1/2] libmakepkg: Fix handling of file paths in get_filepath

[Vladimir Panteleev]

With local sources containing a path component, get_filepath used to
silently discard the non-filename part of the source URI, which led to
uninformative errors (as well as not being able to place source files
in a subdirectory).

Correct this bug by explicitly adding a case for the local protocol,
and appropriately resolve file paths (local or global) to an absolute
one usable by extract_file.
