[yocto] [opkg-utils][PATCH 21/22] opkg.py: use textwrap for description writing

[Martin Jansa]

* description field in oe-core sometimes has extra line-feeds and is long
* extra line-feeds breaks read_control, because empty line means next Package
* long descriptions should be wrapped and properly indented, so they are parsed back properly
