[BPF] fix clang test failure for bpf-attr-preserve-access-index-4.c
Depending on different cmake configures, clang may generate different IR
name for slot variables. Let us use the regex instead of hard coding the
name. I did the same for other bpf-attr-preserve-access-index tests with
such an approach, but somehow did not do for this one.
The file was modifiedclang/test/CodeGen/bpf-attr-preserve-access-index-4.c
