sanitycheck incorrect judgement with tests/drivers/gpio/gpio_basic_api.

[chen-png]

Describe the bug
after connecting gpio pins according to readme file, the tests/drivers/gpio/gpio_basic_api/ is passed, but it would be judges as failed by sanitycheck script.

it occurred on frdm_k64f, sam_e70_xplained, mimxrt1050_evk board.

To Reproduce

1. used west to build, it could get the "project execution successful" from serial.
2. ran this test using sanitycheck alone, it also was passed.
3. but if ran the whole tests directory using sanitycheck, this test was always judged as failed.

Screenshots or console output

could see the test output in hander.log and it was successful, but it was judged as failed
