This commit makes periodic RAs from OVN consistent with the RAs sent in
response to RSs. Specifically, this ensures that prefix flags are set
correctly for each address mode.
This commit also gets rid of some redundant definitions for RA prefix
option flags from packets.h in favor of the ones in ovn-l7.h.
