JDK-8294316 - SA core file support is broken on macosx-x64 starting with macOS 12.x
Description
Sometimes SA fails to startup with the following error message:

ERROR: failed to workaround classshareing
Unable to open core file 

The code in question is init_classsharing_workaround() in ps_core_common.c. There a number of reasons why the class sharing work around can fail, and the reason is usually pretty well described with a print_debug() statement. However, since this is an error, these should really just be print_error() statements so the user doesn't need to figure out how to get more info by setting LIBSAPROC_DEBUG (which may also produce a ton of output unrelated to the error).
