package_ipk: allow to specify OPKG_ARGS in local.conf

If user specific parameters to opkg are set in local.conf, they are
rewritten in package_ipk.bbclass and ignored, instead append
package_ipk specific arguments to the user defined ones.

The change is needed, if a user has to pass an alternative path to a
temporary directory for opkg, e.g.

  OPKG_ARGS = "--tmp-dir=${TOPDIR}/tmp-opkg"

The default /tmp directory may be unusable for do_rootfs task, for
example if there is no enough space or /tmp is mounted with noexec
mount option, then an alternative path allows to complete do_rootfs
and fix the problems like this:

  ERROR: Unable to install packages.
