remote_access.sh: remove dependence on ssh-agent

remote_access.sh: remove dependence on ssh-agent

This is take 2 of this CL. Modified run_remote_test.sh to
explicitly start an ssh-agent if necessary instead of
implicitly relying on remote_access.sh to do it.

BUG=n0ne
TEST=Verified I could successfully ssh.

You can't have an empty function in bash. I don't want to remove this
function because its called by clients and we may need to do some cleanup
later. Rather than change the interface, I'm leaving this as an empty
function.

I've added a comment to make this clearer.
