test(integration): add Misc family tracing coverage
Add a misc-basic ioworkload scenario and an end-to-end integration test
for the previously-uncovered Misc syscall family.
The scenario exercises only the safe, unprivileged, non-blocking,
side-effect-free Misc syscalls: getcpu (raw SYS_GETCPU), uname /
sys_newuname (unix.Uname), sysinfo (unix.Sysinfo), vmsplice into a
self-created and self-drained pipe with a tiny buffer, and alarm(0) to
cancel any pending alarm. Code comments document why the remaining Misc
syscalls are intentionally excluded (CAP_SYS_ADMIN / global host
mutation, CAP_SYS_RAWIO / x86-only, Linux 6.13+ availability,
runtime-managed, or not user-callable).
misc_test.go asserts enter_getcpu, enter_newuname, and enter_sysinfo are
each traced at least once for the ioworkload process, restricting tracing
to the issued syscalls and keeping the existing PID/comm hermetic guards.
