The following tests use PKCS11Test.isBadNSSVersion() to determine if they should be skipped.

- TestCurves
- TestECDH2
- TestECDSA
- TestECDSA2
- TestECGenSpec

The `isBadNSSVersion()` method converts the version number to a double and checks if the version is greater than 3.11 but less than 3.12. The current NSS version number is 3.111 which causes the test to be skipped.

Update the logic to correctly handle major/minor version numbers. However, because NSS is so far beyond 3.11 and 3.12, can we just remove the method entirely?
