Fix a memory leak in PKCS #8 load_key and encrypt_key that would

occur because PKCS #5 v2.0 doesn't support empty passphrases (though
maybe it should?). In this case pbe->set_key would throw an exception,
causing the stack to be unwound without the (dynamically created) PBE
object being deleted. Use auto_ptr to hold the PBE*, then .release()
it when passing it to the Pipe (since Pipe takes ownership of its Filters).

Noticed when looking at valgrind analysis of monotone's sync command.
