[MPlayer-dev-eng] [PATCH 2/2] sub/subreader: Use matching pointer type for enca_sub_cp

[Alexander Strasser]

The guess_cp function returns `const char *`, so we should
use the same type for enca_sub_cp as well.

Avoids this warning:

```
sub/subreader.c: In function 'subcp_open':
sub/subreader.c:1287:33: warning: assignment discards 'const' qualifier from pointer target type [-Wdiscarded-qualifiers]
 1287 |                     enca_sub_cp = guess_cp(st, enca_lang, enca_fallback);
      |
```
