[pacman-dev] [PATCH v2] makepkg-template: support multiple --template-dirs

Especially when maintaining local templates in addition to the ones
stored in /usr/share/makepkg-template, it can be useful to include
templates stored in multiple different locations into one PKGBUILD. This
patch makes this possible by allowing --template-dir to be specified
multiple times.
If a template of the same name is present in more than one of the given
directories, the last one always takes precedence.
Neither the default behaviour without the option given, nor the handling
of a single template dir is changed.

v2: - Templates are always checked to exist before process_file is ever
called, so I moved the error message used therein up. No need for
a new string any more.
- Tests were adapted to the slight message and error code changes.
