[PATCH v2 3/4] Accept failing with EPERM in addition to ENOKEY for rename without key

[David Oberhollenzer]

Some filesystems (e.g. UBIFS) fail with EPERM when trying to move a
file into an encrypted directory via cross rename, without having
access to the encryption key.

Since rename is perfectly allowed to return EPERM, which is also tested
for, and no precise specification seems to exist that clarifies when to
expect EPERM and when ENOKEY, this patch modifies the generic/398 test
to accept both, for the test case where the key is not available.
