rootfs_ipkg: fix BAD_RECOMMENDATIONS handling

If multiple versions of the same package are in the package feed then the
generate status file would only contains a "deinstall" status for the last one,
which meant that BAD_RECOMMENDATIONS wouldn't actually work.

Use awk instead of grep and stop reading when we reach a newline, so we only
ever output a single stanza.
