  perf libbfd: Ensure libbfd is initialized prior to use (2025-11-13 17:55:19 -0300)

----------------------------------------------------------------
perf tools fixes for v6.18: 2nd batch

- Fix writing bpf_prog (infos|btfs)_cnt to data file, to not generate
  invalid perf.data files in some corner cases.

- Fix 'perf top' segfault by ensuring libbfd is initialized. This is an
  opt-in feature due to license incompatibilities.

- Fix segfault in 'perf lock' due to missing kernel map.

- Fix 'perf lock contention' test.

- Don't fail fast path detection if binutils-devel isn't available.

- Sync KVM's vmx.h with the kernel to pick SEAMCALL exit reason.
