These were broken in 3aec776fc796 when they were converted
away from using support.run_unittest().  Oops :)

Initial patch by Felippe da Motta Raposo.

Before the argparse conversion, compileall would (sometimes) accept multiple
paths when -d was specified.  Afterward, it does not.  The corresponding check
in the original code claimed to prevent multiple *directories* from being
specified...but it didn't really work even to do that.  So this patch fixes
the regression by invoking the consenting adults rule: if you specify a
combination of arguments to compileall that produces files with inconsistent
destdirs (which you could do before), it is on you.

Initialize package before calling find_spec() for __main__, so that we do not
incorrectly handle exceptions from __init__.py. When runpy is used from the
Python CLI, use an internal exception rather than ImportError, to avoid
catching unexpected exceptions.

Also remove exception message rewriting in _run_module_as_main(), because it
seems to be redundant with the _get_main_module_details() function.
