[PATCH] selftests/powerpc: Add SPDX-License-Identifier to count_stcx_fail.c

[TAO Ye]

count_stcx_fail.c still carries only the original free-text license
notice ("Licensed under GPLv2.") and has no SPDX-License-Identifier
tag.

Replace the free-text notice with the equivalent SPDX identifier
GPL-2.0-only, matching the sibling files. The copyright notice is
retained and no license change is intended.
