bridge: vlan: add global mcast_startup_query_interval option 

Add control and dump support for the global mcast_startup_query_interval
option which controls the interval between queries in the startup phase.
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.
Syntax:
 $ bridge vlan global set dev bridge vid 1 mcast_startup_query_interval 15000
