RFR: 8355439: Some hotspot/jtreg/serviceability/sa/* tests fail on static JDK due to explicit checks for shared libraries in process memory map

[Jiangli Zhou]

Please review the change for following hotspot/jtreg/serviceability/sa/* tests to not check for JDK/VM shared libraries when running on static JDK.

- test/hotspot/jtreg/serviceability/sa/ClhsdbPmap.java
- test/hotspot/jtreg/serviceability/sa/sadebugd/PmapOnDebugdTest.java
- test/hotspot/jtreg/serviceability/sa/sadebugd/RunCommandOnServerTest.java

I tested the change on a `static-jdk` binary with a `static-jdk/bin/jhsdb` symlink to the `jhsdb` in a regular JDK binary. The tests pass with the change. Example test command:

$ make test TEST="serviceability/sa/sadebugd/RunCommandOnServerTest.java" JDK_UNDER_TEST=/<snip>/JDK-8355439/build/linux-x86_64-server-fastdebug/images/static-jdk JDK_FOR_COMPILE=/<snip>/JDK-8355439/build/linux-x86_64-server-fastdebug/images/jdk
