perf trace beauty prctl: Generate 'option' string table from kernel headers

perf trace beauty prctl: Generate 'option' string table from kernel headers

This is one more case where the way that syscall parameter values are
defined in kernel headers are easy to parse using a shell script that
will then generate the string table that gets used by the prctl 'option'
argument beautifier.

This way as soon as the header syncronization mechanism in perf's build
system detects a change in a copy of a kernel ABI header and that file
is syncronized, we get 'perf trace' updated automagically.

Further work needed for the PR_SET_ values, as well for using eBPF to
copy the non-integer arguments to/from the kernel.

E.g.: System wide prctl tracing:
