RFR: 8275687: runtime/CommandLine/PrintTouchedMethods test shouldn't catch RuntimeException

[Fairoz Matte]

During the review of https://github.com/openjdk/jdk/pull/5231#pullrequestreview-784995993 
It was suggested by @iklam in the test case Runtime exception is not required for the reason TouchedMethodsDCmd is always enabled as long as the current JVM has INCLUDE_SERVICES is true.

Igor has agreed to capture this in separate RFE (current) to handle this scenario.

This is trivial, please review.
