RFR: 8347496: Test jdk/jfr/jvm/TestModularImage.java fails after JDK-8347124: No javac

[Severin Gehwolf]

Please review this test-only fix. Apparently there are some test configurations out there that run `jdk/jfr/jvm/TestModularImage.java` with limited modules. Specifically `--limit-modules java.base,jdk.jfr`. For this particular test that is not sufficient to be able to run the test. `TestModularImage.java` uses the `ToolProvider` API to get a hold of `javac` as well as for `jlink` without them being present the test should be skipped.

I've done that by adding those two required modules in the `@modules` tag.

Testing:
- [ ] GHA
- [x] `jdk/jfr/jvm/TestModularImage.java` with test option `--limit-modules jdk.jfr,java.base` which now skips the test (instead of failing the test). Running `TestModularImage.java` without the `--limit-modules` option and it passes.

Thoughts?
