Add support for BAD_RECOMMENDATIONS to rootfs_ipk

As discussed on IRC on 30/06/11, this patch adds support for
BAD_RECOMMENDATIONS to rootfs_ipk, which is a list of packages NOT to
install if suggested or recommended by a recipe.  Taken from
http://thread.gmane.org/gmane.comp.handhelds.openembedded/30417.

Note that current support for this in oe.dev may also be broken,
depending on the version of opkg in use.
