LibretroAdmin 575e331fd1 If we already know the length of the string, use strldup instead. 
Avoids the internal strlen call inside strdup, and strdup is a deprecated
function starting from MSVC2005 anyways.

NOTE: Do NOT pass STRLEN_CONST as n parameter to strldup, it needs to
be at least +1 character higher than the strlen return value of the same
string
