Subject: Add support for all bzr URLs in the PKGBUILD source array

Add support for all bzr URLs, including "lp:" URLs, in the source array.
This, however, requires an internet connection and will fall back to the
current behavior for offline builds. In that case, only the URL reported
by 'bzr config parent_location' run inside the local repo can be used,
and is outputted.
