font-patcher: Remove leftover code

[why]
There is a bit of code that is not needed anymore (or was never needed).
This makes things look more complicated than they are.

[how]
1. It is plain wrong to write that we add one (1) glyph if we do not add
   any glyph.
2. One (1) is added to index later anyhow, so we do not need to distort
   the counting in the beginning (the code will run with index=1 for
   both the first and the second patched in glyph).
