RFR: 8306282: Build failure linux-arm32-open-cmp-baseline after JDK-8257967 [v2]

[Markus Grönlund]

> Greetings,
> 
> With [JDK-8257967](https://bugs.openjdk.org/browse/JDK-8257967), much refactoring was done to the JVMTI code concerning agents. However, some platforms do not have JVMTI support, and tier5 of testing builds an embedded build,  linux-arm32-open-cmp-baseline, which failed because the refactoring did not properly handle conditional compilations for JVMTI.
> 
> JDK-8257967 did run tier5, but it used an existing build, so it did not cause recompilations of the embedded target :-(
> 
> This changeset adds the conditional constructs to let linux-arm32-open-cmp-baseline build successfully.
> 
> It does not look good, but there you go...
> 
> Testing:
> 
> Building: linux-arm32-open-cmp-baseline
> Building: regular platforms
> 
> Thanks
> Markus
