8269077: TestSystemGC uses "require vm.gc.G1" for large pages subtest

[stefank]

The invocation that runs with large pages are guarded with @require vm.gc.G1 and doesn't explicitly state that G1 should be used.

This means two things:

1. We are not running the large pages subtest when other GCs are specified
2. Under some circumstances another GC is ergonomically selected and we run the test with that GC even though the test was guarded by @require vm.gc.G1.

I propose that we move the subtest to its own run section, without any requirement about the used GC.
