natSystem.cc (getpwuid_adaptor): New overloaded function that detects the signature of getpwuid_r.

* java/lang/natSystem.cc (getpwuid_adaptor): New overloaded
function that detects the signature of getpwuid_r.
(init_properties): Use it.
* java/util/natDate.cc (ctime_adaptor): Likewise for ctime_r.
(toString): Use it.
