perf bench syscall: Fix __NR_execve undeclared build error (2023-05-19 12:08:00 -0300)

----------------------------------------------------------------
perf tools fixes for v6.4:

- Fail graciously if BUILD_BPF_SKEL=1 is specified and clang isn't available.

- Add empty 'struct rq' to 'perf lock contention' to satisfy libbpf 'runqueue'
type verification. This feature is built only with BUILD_BPF_SKEL=1.

- Make vmlinux.h use bpf.h and perf_event.h in source directory, not system
ones that may be old and not have things like 'union perf_sample_weight'.

- Add system include paths to BPF builds to pick things missing in the headers
included by clang -target bpf.

- Update various header copies with the kernel sources.

- Change divide by zero and not supported events behavior to show 'nan'/'not
counted' in 'perf stat' output. This happens when using things like
'perf stat -M TopdownL2 true', involving JSON metrics.

- Update no event/metric expectations affected by using JSON metrics in
'perf stat -ddd' perf test.

- Avoid segv with 'perf stat --topdown' for metrics without a group.

- Do not assume which events may have a PMU name, allowing the logic to keep an
AUX event group together. Makes this usecase work again:

$ perf record --no-bpf-event -c 10 -e '{intel_pt//,tlb_flush.stlb_any/aux-sample-size=8192/pp}:u' -- sleep 0.1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 0.078 MB perf.data ]

- Add a check for the above use case in 'perf test test_intel_pt'.

- Fix build with refcount checking on arm64, it was still accessing fields that
need to be wrapped so that the refcounted struct gets checked.

- Fix contextid validation in ARM's CS-ETM, so that older kernels without that
field can still be supported.

- Skip unsupported aggregation for stat events found in perf.data files in 'perf script'.

- Add stat test for record and script to check the previous problem.

- Remove needless debuginfod queries from 'perf test java symbol', this was
just making the test take a long time to complete.

- Address python SafeConfigParser() deprecation warning in 'perf test attr'.

- Fix __NR_execve undeclared on i386 'perf bench syscall' build error.
