net: disable BRIDGE_NETFILTER by default

The description says 'If unsure, say N.' but
the module is built as M by default (once
the dependencies are satisfied).

When the module is selected (Y or M), it enables
NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS
which alter kernel internal structures.

We (Android Studio Emulator) currently do not
use this module and think this it is more consistent
to have it disabled by default as opposite to
disabling it explicitly to prevent enabling
NETFILTER_FAMILY_BRIDGE and SKB_EXTENSIONS.
