[Graal] serviceability/jvmti/GetModulesInfo/JvmtiGetAllModulesTest.java fails with Graal in Xcomp mode

serviceability/jvmti/GetModulesInfo/JvmtiGetAllModulesTest.java fails when running with
"-Xcomp -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+TieredCompilation -XX:+UseJVMCICompiler -Djvmci.Compiler=graal" flags.

The cause is because Graal is getting initialized somewhere between
ModuleLayer.boot().modules() and getModulesJVMTI() calls.
As result getModulesJVMTI() returns 2 more additional modules jdk.proxy1 and jdk.proxy2 which
are dynamically created during Graal initialization.

To reproduce the issue you can compare output of
"java -verbose:module -version" and
"java -Xcomp -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCI -XX:+TieredCompilation -XX:+UseJVMCICompiler -Djvmci.Compiler=graal -verbose:module -version"

To run serviceability/jvmti/GetModulesInfo/JvmtiGetAllModulesTest.java do
