selftests/empty_mntns: fix wrong CLONE_EMPTY_MNTNS hex value in comment

Browse Source 
CLONE_EMPTY_MNTNS is (1ULL << 37) = 0x2000000000ULL, not 0x400000000ULL.

* These tests exercise the clone3() code path for creating empty mount
* namespaces, which is distinct from the unshare() path tested in
* empty_mntns_test.c. With clone3(), CLONE_EMPTY_MNTNS (0x400000000ULL)

* is a 64-bit flag that implies CLONE_NEWNS. The implication happens in
* kernel_clone() before copy_process(), unlike unshare() where it goes
* through UNSHARE_EMPTY_MNTNS -> CLONE_EMPTY_MNTNS conversion in
