font-patcher: Use WIN metrics in all conflicting cases

[why]
When HHEA and (depending on USE-TYPO-METRIC) TYPO or WIN are not
consistent it is unclear which metric we should trust.

In #1056 the complete font bounding box (i.e. yMin and yMax) has been
compared to the baseline to baseline distances, and in all these cases
the WIN values seem to be best (preserve the glyph bounding box).

    font-line report fontname.ttf | grep metrics:
    ttfdump -t head fontname.ttf | grep "yM(in|ax)"

[note]
Roboto will still be clipped?! There seem to be ridiculously high glyphs
in there. Did not check which.
