run_remote_tests.sh: allow testing with offline remote hosts

Useful for tests that do not require SSH access, such as those that use
servo for initializing the DUT. An SSH initialization is still
attempted, but is not required to succeed if --allow_offline_remote is
used.

BUG=None
TEST=Test continues in the presence of SSH connection timeout
