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.

perf libbfd: Ensure libbfd is initialized prior to use

Multiple threads may be creating and destroying BFD objects in
situations like `perf top`.

Without appropriate initialization crashes may occur during libbfd's
cache management.

BFD's locks require recursive mutexes, add support for these.

Committer testing:

This happens only when building with 'make BUILD_NONDISTRO=1' and having
the binutils-devel package (or equivalent) installed, i.e. linking with
binutils devel files, an opt-in perf build.

Before:

  root@x1:~# perf top
  perf: Segmentation fault
  -------- backtrace --------
  <SNIP multiple failed attempts at printing a backtrace>
  root@x1:~#

After this patch it works as before.
