RFR: 8209092: Remove outdated wording from RC5ParameterSpec

[Ben Perez]

The RC5ParameterSpec class description contains the following sentence: "This class can be used to initialize a Cipher object that implements the RC5 algorithm as supplied by RSA Security LLC, or any parties authorized by RSA Security." 

The part "as supplied by RSA Security LLC, or any parties authorized by RSA Security." should be removed. We don't generally include information about 3rd-party JCA providers in the standard javadocs.
