test: allow multiple config options in buildconfigspec

In some cases we have alternative configuration options that supply the
same functionality, e.g CONFIG_NET and CONFIG_NET_LWIP.

Allow to specify all of them as arguments for buildconfigspec() and execute
the text if any of these is fulfilled, e.g.

    @pytest.mark.buildconfigspec('net', 'net_lwip')

Update the documentation.
