[PATCH] Add const qualifier for charset_name in init_dfa

[Vladimir 'φ-coder/phcoder' Serbinenko]

In GRUB charset is hardwired to UTF-8 and we return just a pointer to
"UTF-8" in nl_langinfo (CODESET);
I propose adding const qualifier since this function already handles
codeset_name as a pointer to const string.
