[yocto] [OE-core] [PATCH] opkg-utils: update-alternatives fails for "[" and "[[" in busybox

[Liu Jian]

Building a small filesystem with busybox gives the following error lines:
sed: -e expression #1, char 41: unterminated address regex
sed: -e expression #1, char 42: unterminated address regex
This is caused by the script update-alternatives.
"[" can not be used directly in sed expression.
