recipetool: create: determine name/version from github/bitbucket URLs

Both BitBucket and GitHub provide "release" downloads that unfortunately
don't include the actual project name. For recipetool this means we have
to have special handling for these URLs or else the current code assumes
the name of the project is something like "v0.9.1". Borrow and adapt
some code from autospec to do this, and put it in its own function for
clarity.
