Disable dtrace for jdk17 on Linux ppcle

[adamfarley]

Because dtrace has been disabled on jdk17 for linux ppcle.

When this was disabled for later versions of openjdk, we started to see build failures, so we removed that option from our builds. This PR does the same for JDK17 because the aforementioned change was backported to jdk17.

Note: I'm not removing the option from s390x builds because the dtrace disabling that was done on s390x has not (yet, anyway) been backported.
