remote_access.sh: Unset SSH_AUTH_SOCK unless --ssh_allow_agent

It turns out that using SSH_AUTH_SOCK can make ssh connections super
slow to establish in some situations.  Let's remove it unless the user
specifically requests it.

This speeds update_kernel up from ~35 seconds to ~5 seconds on most
Google Engineer's workstations.

BUG=None
TEST=time ./update_kernel.sh --remote=zzz --noreboot --ssh_allow_agent
