Fix cast-align error
If compiler doesn't inline StructAtOffset, this was an error since we
only disable cast-align at call-site. So, move the cast out.
../src/hb-machinery.hh: In instantiation of 'const Type& StructAtOffset(const void*, unsigned int) [with Type = unsigned int]':
../src/hb-font.cc:146:85: required from here
../src/hb-machinery.hh:63:12: error: cast from 'const char*' to 'const unsigned int*' increases required alignment of target type [-Werror=cast-align]
{ return * reinterpret_cast<const Type*> ((const char *) P + offset); }
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
