* [hip-tests] Fix Unit_Assert_Positive_Basic_KernelFail
This test was expecting a call to abort() when assertions
where hit on AMD devices. This is no longer true since
aborts from assertions are disabled unless
HIP_SKIP_ABORT_ON_GPU_ERROR is set.
This PR simplifies the test by removing the SIGABRT signal
handling (which was also undefined behaviour). Instead,
if HIP_SKIP_ABORT_ON_GPU_ERROR is set, the test is skipped.
