Add @RequiresPermission for setUnderlyingNetworks
setUnderlyingNetworks() is mainly for the NetworkAgents who hold
the NETWORK_FACTORY to set its underlying networks.
And the underlying networks are only visible and useful for the
caller of getNetworkCapabilities() or the receiver of
onCapabilitiesChanged() who hold one of NETWORK_FACTORY,
NETWORK_SETTINGS and MAINLINE_NETWORK_STACK permissions.
Otherwise, the underlying networks field will be cleard before
sending.
