devtool: add: create git repository if URL specified as positional argument

When we add from a fetched URL we are supposed to turn the resulting
source tree into a git repository (if it isn't already one). However, we
were using the older deprecated option name here instead of the
positional argument, so "devtool add -f <url>" resulted in the repo
being created but "devtool add <url>" didn't, which was wrong.

Also update the oe-selftest tests to check that this worked.
