The d_path selftest fails in local vmtest.sh because /dev/shm is not mounted. Switching the test path to /tmp is not an option because /tmp is a 9p mount in BPF CI, which does not support fallocate(). To ensure tests pass in local vmtest.sh without breaking BPF CI, mount tmpfs on /dev/shm with mode=1777 in mkrootfs_tweak.sh. Signed-off-by: Pu Lehui <pulehui@gmail.com>
