8285591: [11] add signum checks in DSA.java engineVerify

[gnu-andrew]

This change was part of a security fix, JDK-8277233, for 17u during the April update. The rest of 8277233 did not apply to older releases, as it concerned code added to src/jdk.crypto.ec/share/classes/sun/security/ec/ECDSAOperations.java by JDK-8237218 in 15u.

However, the additional checks in src/java.base/share/classes/sun/security/provider/DSA.java that were included in the patch are applicable to older releases.
