Some cleanup on Layer_Freetype

Yes, I know probably all this layer will be replaced by Pango rendering instead of direct usage of FreeType library.
However, I'm having some size/position difference issues with this replacement. So, for now, let me improve this layer…

@ice0 could this be a CMake specific issue?

[ice0]

@rodolforg sure. CMake still could have different compilation flags and defines. I will take a look.

The problem is in that place:

// special_family.option3 = nullptr
possible_families.push_back(special_family.option3);

This does not happen when FontConfig is installed, but it may need to be considered.

Now it fails because of this:

// i = 6; (but special_font_family_db has only 5 items)
for (int i = 0; special_font_family_db[i].alias; i++) {

I changed it to:

int count = sizeof(special_font_family_db) / sizeof(special_font_family_db[0]);
for (int i = 0; i < count && special_font_family_db[i].alias; i++) {

P.S. Fixed CMake FontConfig search, please rebase.

Merged. Thank you!
