update.py: use reader to decode subprocess output correctly

We can't decode UTF-8 characters byte-by-byte, as soon as we hit a
character that's more than one byte long then we'll fail. Use a reader
object to do it properly. This fixes parsing current meta-angstrom on
master. At the same time, specify errors="surrogateescape" to avoid the
update process dying at this point in case of characters that aren't
valid UTF-8.

Thanks to Jiajie Hu <jiajie.hu@intel.com> who fixed this in devtool's
very similar code.
