support .fdroid.* metadata file in source root of app being built

This allows app makers to include a .fdroid.(json|xml|yaml|txt) metadata
file in the root of the git repo of their app, then they can build it using
`fdroid build`.  This is useful for developers who want to maintain the
fdroid build recipe themselves, and run the fdroid build process for their
own builds.
