Allow using locales when gettext is absent

Previously, if configure did not detect dgettext(), we disabled
anything that smelled like localization, inadvertently including
setlocale().  Now that we use setlocale(LC_ALL, ""), we have
localized dates available as well as messages, so we should not
disable calls to setlocale() any more.
Since the routines from locale.h are only used in a relatively
small number of places, just include the header directly in those
files and remove it from k5-platform.h.
