[PATCH RESEND 1/2] gpu: Fix dependencies in CONFIG_GPU_BUDDY_KUNIT_TEST

CONFIG_GPU_BUDDY is currently not selectable by the user, mirroring
how CONFIG_DRM_BUDDY does it - the idea is for a driver that makes use
of it to include a "select GPU_BUDDY" line in its kconfig.
CONFIG_DRM_BUDDY is also selected when building with
CONFIG_DRM_KUNIT_TEST, as it can be thought of as building a mock
"driver" running the tests, that makes use of the buddy functionality.

CONFIG_GPU_BUDDY_KUNIT_TEST doesn't follow that logic, requiring
GPU_BUDDY to be selected already instead of selecting it itself. This
requires building the test kernel with another driver that uses
DRM_BUDDY, as this is currently the only kconfig option that selects
GPU_BUDDY. That shouldn't be required to run unit tests for a module
now completely independent from DRM, let alone any specific driver.

Fix the dependency declaration in CONFIG_GPU_BUDDY_KUNIT_TEST to make it
work as intended, mirroring the setup in CONFIG_DRM_KUNIT_TEST.
