Port failed-syscalls-by-pid.py to a standalone script in
tools/perf/python/ using the perf module:
- Resolve architecture-aware syscall names using
perf.syscall_name(id, session.e_machine) instead of host python-audit
tables, supporting cross-architecture perf.data files without external
dependencies.
- Translate negative syscall return values into symbolic E* error names
using perf.arch_strerrno(ret, session.e_machine), leveraging the
auto-generated trace beauty architecture errno tables.
- Encapsulate aggregation in a SyscallAnalyzer class using
collections.defaultdict and add argparse filtering by comm, PID, and
-i/--input.
Add a shell test (test_failed_syscalls_by_pid_python.sh) to verify the
standalone script.
