Lőrinc 63b6b638aa build: Use character literals for generated headers to avoid narrowing
Use character literals instead of integer hex values (i.e. `'\x5b','\x0a', ...` instead of `0x5b, 0x0a, ...`) for generated headers.
This avoids C++11 narrowing warnings in a more concise way than using explicit char casts.

Extra whitespace is also removed between elements for brevity.
