Trailing whitespace in pem test vector

[kaduk]

vectors/cryptography_vectors/asymmetric/Traditional_OpenSSL_Serialization/key1.pem has a trailing space character on the last line ("-----END RSA PRIVATE KEY----- "). This causes a failure in the openssl test suite when I attempt to apply strict whitespace checking for private key loading. (Arguably openssl should not break compatibility like that in a major release series, so I will back out that change, but did want to point out that there is trailing whitespace here, in case it is desired to remove it.)

That vector is originally from OpenSSL's tests, so if upstream would like to remove the trailing whitespace, I have no problem doing so. Do you want to send a PR?

Err, sorry that one comes from gnutls, but the space is something we added by accident:

👍 to removing the trailing whitespace
