Missing doPriviliged in deprecation logger

[pgomulka]

possibly a doPriviliged in deprecation logger together with a test DeprecationLoggerTests.testLogPermissions
were accidentally removed.
This is possibly a regression.

Scripts run under reduced privileges. (can @elastic/es-core-infra help?) and
the test was introduced to verify deprecation logger not violating Security Manager permission when rolling over the files.

However the doPriviliged call in deprecation logger was removed in (7.10+) https://github.com/elastic/elasticsearch/pull/55941/files#diff-593ea478a0a8d462fd38ad70838ee6e4a28673478d28812c48d9ed5cf768c132L249

The test itself was removed in 7.10+

@stu-elastic or @jdconrad do you remember more context about this? Do you think this should be fixed?

@pgomulka It does indeed appear this is a regression based on your findings here. Reading back through (#28485) and (#37281) confirms log rollover will fail w/o the doPrivileged call if executed directly from a script. This is going to be necessary until security manager is removed in its entirety.

@nik9000 Would you please take a look at this to make sure I haven't overlooked anything?

I think you are correct, we should revive this test and get it passing.
