Subject: PRNGLocker: disable copy and move

Axivion (SV61) points out based on Qt-RuleOfThree the lack of copy and
move constructors and operators.
We don't need them, so tell the compiler not to create them.

As a drive-by change mark the constructor as explicit and not
discardable.

Task-number: QTBUG-122619
Pick-to: 6.7 6.5
