Fix HotSpot VM build without JVMTI

Sanne reported on leyden-dev [0] about his experiment to build openjdk without jvmti. He reported compilation failures in the leyden-premain specific code. After fixing those issues the build still failed and the failures are not related to the premain code. The same failures can be reproduced in the mainline code when jvmti feature is excluded during the configure step.

Steps to reporoduce:

$ bash ./configure --with-conf-name=no-jvmti-release --with-jvm-features=cds,compiler1,compiler2,g1gc,serialgc,jfr,jni-check,jvmci,management,services --with-jvm-variants=custom

$ make images CONF=no-jvmti-release
