oggenc: remove unused option -A, fix opt string
The -A option (was previously short for --advanced-encode-option) to oggenc hasn't been valid since , but the getopt string still finds it and expects an argument... but it doesn't actually do anything. The patch removes the -A option.
Additionally, the -l (--album) option wasn't specified in the short arguments as requiring an option, but this didn't cause an actual problem on my system. It's semantically correct after applying the patch.
