Subject: [PATCH] Allow building libsigrok without libserialport.

Since the DER EE DE-5000 driver is currently the only user of
the es51919 module and it depends on the libserialport, compile
the module only if the DER EE DE-5000 driver is enabled. This
allows libsigrok to be built without libserialport again.
