real_path: prevent redefinition of MAXSYMLINKS

Browse Source 
The macro 'MAXSYMLINKS' is already defined on macOS and Linux in
<sys/param.h>.  If 'MAXSYMLINKS' has already been defined, use the value
defined by the OS otherwise default to a value of 32 which is more
inline with what is allowed by many systems.
