openjade-native: Ensure we reautoconf the package

Currently since configure.in in is in a subdirectory, we don't reautoconf the
recipe. We really need to do this, to update things like the libtool script used
and fix various issues such as those that could creep in if a reautoconf is
triggered for some reason. Since this source only calls AM_INIT_AUTOMAKE to gain the
PACKAGE and VERSION definitions and that macro now errors if Makefile.am doesn't
exist, we need to add these definitions manually.

These changes avoid failures like:
