ip: xfrm: Fix policy and state flags.

o Support policy flag with string format.
  Note that kernel defines only one name "localok" for the flag
  and it has not had any effect currently.
o Support state flag value XFRM_STATE_NOPMTUDISC.
o Fix to show detailed flags value when "-s" option is used.
o Fix minor typo.
