vfs: update ctime when changing the file's permission by setfacl
generic_acl_set didn't update the ctime of the file when its permission was
changed.
Steps to reproduce:
# touch aaa
# stat -c %Z aaa
1275289822
# setfacl -m 'u::x,g::x,o::x' aaa
# stat -c %Z aaa
1275289822 <- unchanged
But, according to the spec of the ctime, vfs must update it.
