Fix test_create_jks_success failing on SELinux machine (#42001)

Currently TestCreateJavaKeystore::test_create_jks_success is failing on
a machine with SELinux because set_context_if_different is not mocked
and hence tries to access a file that doesn't exist because it has been
mocked previously.

Also, changing path to a path that won't exist for sure.
