ls-remote: pass heads/tags prefixes to transport

Unlike its arbitrary text patterns, the --heads and --tags
options to ls-remote are true prefixes. We can pass this
information to the transport code. If the v2 protocol is in
use, that will reduce the size of the ref advertisement.

Note that the test added here succeeds both before and after
the patch. This is an optimization, not a bug-fix; it's just
making sure we didn't break anything.
