When rename("a", "b/.") is performed, target namei() call returns
dvp == vp. Rename syscall does not check for the case, and at least
ufs_rename() cannot deal with it. POSIX explicitely requires that both
rename(2) and rmdir(2) return EINVAL when any of the pathes end in "/.".

Detect the slashdot lookup for RENAME or REMOVE in lookup(), and return
EINVAL.
