package/u-boot-envtools: update to version 2011.06. This updates uboot-envtools to the version which comes with U-Boot 2011.06. The important novelity is that fw_setenv now supports batch processing, which greatly improves sysupgrade of the ALL0258N as otherwise we would have to overwrite uboot-env up to 8x in a single firmware upgrade. Unfortunately, no newer version of the sources is available from Debian, so we got to take it from the u-boot source which is kinda ugly...
