sys/linux: prohibit EXT4_IOC_RESIZE_FS
When we run with sandbox=none, test program can do EXT4_IOC_RESIZE_FS which
shrinks rootfs basically to 0. This breaks the machine as all tests then fail with:
failed to create temp dir: mkdir syzkaller-testdir077269498: no space left on device
This is the most common source of "lost connection" crashes overall and
they are not actually kernel bugs.
Prohibit EXT4_IOC_RESIZE_FS for now.
Alternatively we can mount tmpfs with sandbox=none.
Update #971
