RFR: JDK-8289569: [test] java/lang/ProcessBuilder/Basic.java fails on Alpine/musl

[Matthias Baesken]

Currently the ProcessBuilder/Basic.java test fails on musl.
We run into
>'java.io.IOException: Cannot run program "./prog": error=8, Exec format error
at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1143)
at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1073)
at Basic.run(Basic.java:2771)
at Basic$JavaChild.main(Basic.java:498)
Caused by: java.io.IOException: error=8, Exec format error
at java.base/java.lang.ProcessImpl.forkAndExec(Native Method)
at java.base/java.lang.ProcessImpl.<init>(ProcessImpl.java:319)
at java.base/java.lang.ProcessImpl.start(ProcessImpl.java:249)
at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1110)
... 3 more

This seems to be a musl/Alpine specific issue with some process execs.
So adding !vm.musl to the test might make sense.
