sun/security/krb5/auto/Cleaners.java fails on jdk19 alpine-linux

As seen in https://github.com/adoptium/aqa-tests/issues/4257#issuecomment-1396446238, this extended.openjdk testcase has been failing consistently since Nov 20th. Fails on test-docker-alpine314-x64-1 and test-docker-alpine314-x64-2 and possibly elsewhere.

`Execution failed: `main' threw exception: java.lang.Exception: Proc abnormal end `

Start with sun/security/krb5/auto/Cleaners.java, especially the failure at Cleaners.java:106, and inspect jdk.test.lib.process.Proc.readData at Proc.java:377. Reproduce the test on test-docker-alpine314-x64-1 or test-docker-alpine314-x64-2 and determine why the process ends abnormally; done means the testcase passes on the affected Alpine environments.
