[PATCH v2 net-next 3/7] selftests: openvswitch: Add set() and set_masked() support.

[Aaron Conole <aconole@redhat.com>]

These will be used in upcoming commits to set specific attributes for
interacting with tunnels.  Since set() will use the key parsing routine, we
also make sure to prepend it with an open paren, for the action parsing to
properly understand it.
