Improve mapping between Font Config and Qt font attributes

It was sometimes impossible to select the desired font due to the code
completely ignoring the FC_WIDTH attribute and poor mapping of the
FC_WEIGHT attribute. The result was that it was easy to have a font file
that was inaccessible by Qt since it shared attributes with another
font file.

The FC_WIDTH attribute is now fetched and used unchanged as the font's
stretch value other than ensuring it is within the allowed range.

For FC_WEIGHT, the code no longer matches the value with the closest
QFont::Weight enum but instead does a piecewise linear mapping so
that Qt enum values match Font Config ones to the extent possible.

Also removed bogus call to fetch the width that was doing nothing with it.
