[PATCH 1/1] opkg_svn: update-alternatives fails for "[" and "[[" in busybox

[Liu Jian <jian.liu@windriver.com>]

Building a small filesystem with busybox gives the following error lines:
(see log.do_rootfs under bitbake_build/tmp/work/)
sed: -e expression #1, char 41: unterminated address regex
sed: -e expression #1, char 42: unterminated address regex
This is caused by the script
bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/update-alternatives.
"[" can not be used directly in sed expression.
