Fix incorrect y-offset for text in i3bar (2)

014aa7ff7441a8a2bb53bd0956aff61faaf6f37f fixed incorrect align of small
symbols, but also introduced a problem with texts with mixed large and
normal symbols. Fix it by centering the text vertically only if its
height is smaller that the saved font height.
Fixes #1543.
