perf/core improvements and fixes:
BPF:
Song Liu:
- Fix synthesized PERF_RECORD_KSYMBOL/BPF_EVENT
Arnaldo Carvalho de Melo:
- Add bpf_map() helper, to make BPF map declararions more compact and
allow for BTF annotations to be made transparently.
perf script python:
Tony Jones:
- Remove explicit shebangs.
- Fix the PYTHON=python3 builds.
Core:
Davidlohr Bueso:
- Update rbtree implementation, getting it closer to the kernel one.
- Use cached rbtrees.
Arnaldo Carvalho de Melo:
- Remove some needless headers from .c and .h files fixing up the fallout,
to reduce building time when changes are made to .h files

perf augmented_syscalls: Convert to bpf_map()
To make the code more compact, end result is the same:
# perf trace -e /home/acme/git/perf/tools/perf/examples/bpf/augmented_syscalls.c sleep 1
0.000 ( 0.008 ms): sleep/9663 openat(dfd: CWD, filename: "/etc/ld.so.cache", flags: RDONLY|CLOEXEC) = 3
0.022 ( 0.005 ms): sleep/9663 openat(dfd: CWD, filename: "/lib64/libc.so.6", flags: RDONLY|CLOEXEC) = 3
0.226 ( 0.006 ms): sleep/9663 openat(dfd: CWD, filename: "/usr/lib/locale/locale-archive", flags: RDONLY|CLOEXEC) = 3
