Bug#914291: jaxrs-api: copyright file wrong

[Emmanuel Bourg]

Control: severity -1 normal

The license changed in the version 2.1.1 because the project was donated
to the Eclipse Foundation. There is no code change between the version
2.1 under the CDDL+GPL and the version 2.1.1 under the EPL+GPL. So it's
still correct to state that the code is licensed under the CDDL.
