There's an alternative to this in patchset 2 - which just changes the
unittest.cc rather than styled_label.cc - but I think this is what we want in
the longer term anyway (i.e. Label and StyledLabel default fonts should match).

(also this is a bit more heavyweight than using ResourceBundle directly, but
keeps the relationship with Label more cohesive, and is a similar approach to
e.g. CalculateLineHeight() in the anonymous namespace)
