ovs-ofctl: Support "send_flow_rem" in "learn" actions.

This flag was overlooked when support for the "learn" action was added.
(It was always supported in the OpenFlow code, just not in the ovs-ofctl
interface.)

ofp-actions: Store cookie in network byte order in struct ofpact_learn.

Most other code in Open vSwitch that works with flow cookies keeps them
in network byte order.  Using network byte order in struct ofpact_learn,
also, reduces the number of byte order conversions needed across the
source tree.
