RFR: 8343293: Remove the check for <apphome>/jre/lib/libjava.dylib from the launcher's java_md_macosx.m

[Jaikiran Pai]

Can I please get a review of this change which cleans up a leftover code from the launcher's java_md_macosx.m file?

In https://bugs.openjdk.org/browse/JDK-8329862 changes were done in the launcher code to remove checks for  `<apphome>/jre/lib/` when determining the JDK installation root. Those changes were done in the Unix and Windows files and the macosx one got left out, likely due to an oversight.

The commit in this PR removes that leftover code.
