Fix to padd incoming ECC signatures correctly.

Description of problem:

Now that we can make ECC signatures, this requires often that the signature data has to be padded or truncated correctly based on what is returned by the card and what is required by NSS.

We already have a method to do this but it only handles the truncation case, not the padding case.

Version-Release number of selected component (if applicable):

Latest rhel5 coolkey

How reproducible:


Steps to reproduce.

1. Enroll a 384 bit or higher token with rhcs ecc upcoming errata candidate.

2. Run BobR's smartcard test program.

Actual results:

Some of the signatures attempted by the tool will fail.

Expected results:

We want all support signature types to be performed correctly.

Since 5.10 is only accepting blocker bugs at this point(they have already built a release candidate), I am recommending that we defer this fix until 5.11 and we consider fixing this in 5.10.z.

tested on RHEL 7 as well. Padding is working correctly.
