[llvm] [BOLT][AArch64] Fix perf2bolt-spe test (PR #162312)

[Paschalis Mpeis via llvm-commits]

https://github.com/paschalis-mpeis created https://github.com/llvm/llvm-project/pull/162312

Lit recently started failing on some machines when using a subshell. The test used a subshell to handle kernels where SPE's brstack option is unavailable (<6.14), but it appears to work without it now.

Tested with perf 6.8 and 6.17.
