Fix loopaesOpen for keyfile on standard input.

Browse Source 
The change in keyfile processing caused that special loopAES
keyfiles are no longer read from stdin if key-file argument is "-".

Fix it by using /dev/stdin in cryptsetup if "-" is detected.
(The libcryptsetup API no longer parses spacial meaning of "-" internally).

Fixes #364.
