factory_test_tools: don't check WP switch status if wpfw won't be executed.

For platforms with buggy write protection switch, we should ignore the switch
status if test list specified not tot enable write protection.

NOTE: This is for R13 factory branch only.

TEST=/gooftool --debug_dryrun_wpfw --verify_switch_wp; echo $? # see 0
