ls-remote: pass ref prefixes when requesting a remote's refs

Browse Source 
Construct an argv_array of ref prefixes based on the patterns supplied
via the command line and pass them to 'transport_get_remote_refs()' to
be used when communicating protocol v2 so that the server can limit the
ref advertisement based on those prefixes.
