[PATCH v2] selftests: gpio: add config fragment for gpio-mockup

[Fathi Boudra]

The gpio test requires to insert the gpio mockup module (CONFIG_GPIO_MOCKUP).
The gpio mockup driver depends on gpiolib (CONFIG_GPIOLIB).
CONFIG_GPIO_SYSFS is selected automatically by the gpio mockup driver.

Tested on x86_64 and arm64 with defconfig and kselftest-merge.

Changes in v2:
 * Per Bamvor Zhang Jian review, add gpiolib dependency (CONFIG_GPIOLIB).
   Skipped CONFIG_DEBUG_GPIO as it isn't necessary, and CONFIG_GPIO_SYSFS
   as it's selected automatically by the gpio mockup driver.
