loadarchive: guard against locale-archive corruption (Bug #25115)
_nl_load_locale_from_archive() checks for a zero size, but divides by both (size) and (size-2). Extend the check to guard against a size of two or less. Tested by manually corrupting locale-archive and running a program that calls setlocale() with LOCPATH unset (size is typically very large). Reviewed-by: Carlos O'Donell <carlos@redhat.com>
