broadcom-wl: don't inherit lock descriptor in nas process

Add a local hack to prevent the Broadcom WPA authenticator process from
inheriting the lock descriptor 1000 used to prevent concurrent executions
of the init script.

Without this fix, repeated invocations of /etc/init.d/network, e.g. for
obtaining the enabled state, would hang forever.
