Songlx516 f820016de3 test(host): fix statvfs shim for big-file e2e; add standalone bigfile driver ...

Host-side verification that the ZIP engine can extract a >4GiB zip64
entry end to end (4.7 GiB fixture, content byte-compared):

- tests/compat/sys/statvfs.h: resolve the path before taking the drive
  letter (relative paths used to fail) and scale f_bavail by 4096 since
  `unsigned long` is 32-bit on Windows and silently truncated ~250GB
  down to ~2.3GB; real 64-bit hosts and the PS5 (LP64) are unaffected.
- tests/bigfile_e2e.c: standalone driver to extract one large archive
  and print the engine result (verification via cmp/sha256 by caller).
- tests/run-tests.sh: incremental clean instead of `rm -rf` of the whole
  build tree.
- Makefile: force -DHAVE_FSEEKO so minizip uses fseeko/ftello instead of
  falling back to fseek/ftell on libcs without the probe.

Result: 4.7 GiB zip64 extracts OK on host in ~6s, output identical to
source. Engine 64-bit write path confirmed clean; PS5 failure needs the
strerror passthrough build for real-machine errno capture.
