build: update spec file to use proper pathex and datas paths (#895)

* build: add "src" to pathex.

Instead of having to pre-install tagstudio, this will have PyInstaller directly build it from source.

* build: be more selective about the data files.

Since PyInstaller builds from source now there is no need to manually add it.
