Denys Smirnov 63626fb251 font/sfnt: fix hmtx table size validation 
The library assumes the hmtx size to be equal to 2*nGlyph + 2*nHm,
which is a simplification of 4*nHm + 2*(nGlyph-nHm) as described
in the spec. However, fonts seen in the wild sometimes omit the
second term (left side bearings), making validation to fail.

CL fixes the validation code by allowing to omit the second term.

Fixes golang/go#28379
