[Libguestfs] [PATCH] fish: drop leading '/' in nbd paths (RHBZ#1379585)



When parsing the URI, drop the leading '/' from the path also when the
protocol is 'nbd': in this case, the path represents the export name,
which does not need the '/' coming from the URI format.

Improve the coverage for nbd in test-add-uri.sh, adding a couple of
tests, and adjusting the result of an existing one.
