RFR: 8322873: Duplicate -ljava -ljvm options for libinstrument

[Mikael Vidstedt]

The libinstrument library is linked against libjava and libjvm, twice. This is mostly harmless but Xcode 15.x generates a warning:

Creating support/modules_libs/java.instrument/libinstrument.dylib from 12 file(s)
ld: warning: ignoring duplicate libraries: '-ljava', '-ljvm'

In particular, note that the `JDKLIB_LIBS` variable passed in to `LIBS` already contains the -ljava -ljvm options. Digging through the history it seems like this issue was introduced with [JDK-8141290](https://bugs.openjdk.org/browse/JDK-8141290).

Testing: tier1,builds-tier[2-5] (in progress)
