test(integration): add cachestat end-to-end coverage
cachestat(2) had no integration coverage. Add a readwrite-cachestat
ioworkload scenario and TestReadwriteCachestat mirroring the readahead
precedent: open a temp file, write data to populate the page cache, then
issue cachestat via a raw syscall (no glibc/unix wrapper) with a whole-file
cachestat_range and zeroed cachestat output buffer, flags=0. ENOSYS on
kernels < 6.5 is tolerated for portability.
The test asserts enter_cachestat is captured with the fd-resolved file
path, that the UNCLASSIFIED return attributes zero bytes, and that the
syscall duration is positive. golang.org/x/sys is promoted to a direct
dependency. Verified PASS under sudo on kernel 7.0.9.
