selftests/bpf: Use CAN_USE_LOAD_ACQ_STORE_REL when appropriate
Instead of open-coding the conditions, use
'#ifdef CAN_USE_LOAD_ACQ_STORE_REL' to guard the following tests:
verifier_precision/bpf_load_acquire
verifier_precision/bpf_store_release
verifier_store_release/*
Note that, for the first two tests in verifier_precision.c, switching to
'#ifdef CAN_USE_LOAD_ACQ_STORE_REL' means also checking if
'__clang_major__ >= 18', which has already been guaranteed by the outer
'#if' check.
