bridge: vlan: add global mcast_membership_interval option 

Add control and dump support for the global mcast_membership_interval
option which controls the interval after which the bridge will leave a
group if no reports have been received for it. To be consistent with the
same bridge-wide option the value is reported with USER_HZ granularity and
the same granularity is expected when setting it.
The default is 26000 (260 seconds).
Syntax:
 $ bridge vlan global set dev bridge vid 1 mcast_membership_interval 13000
