Using iconv with //TRANSLIT is broken on musl libc

[Bevinsky]

Musl iconv does not support the glibc //TRANSLIT extension, but it's still being used:

The changelog for 1.9.10 mentions that the TRANSLIT problem was solved, but the fix was broken and reverted.

Simply removing the TRANSLIT would make getID3 work on musl libc.
