Don't trust character widths for internal OS X fonts in form controls
https://bugs.webkit.org/show_bug.cgi?id=115883
<rdar://problem/13817757>

Reviewed by Darin Adler.

We ignore the character width for a bunch of fonts when predicting
the width of a form control. Some of the internal fonts in OS X are
not in the ignored list. Rather than add them, simply test for
fonts whose family begins with a period character ".".

* rendering/RenderTextControl.cpp:
(WebCore::RenderTextControl::hasValidAvgCharWidth): Return false for
    any family that starts with "."
