Crypto module tests create txt files outside of build directory

This relates to the jaxrs/security/resteasy-crypto module...

When you do a full build (including unit tests) you will see that there are 3 files that have been modified:

• python_encrypted_signed.txt
• smime_signed.txt
• smime_signed_bad.txt

These files are created (or modified) every time the unit tests are run. Artifacts such as these should be under the target folder so that a mvn clean properly disposes and resets the build environment.
