POSIX requires RTLD_LOCAL to be defined in <dlfcn.h>[1].  While our
dlopen() does nothing with its second argument, portable software can
rightfully expect the definition to exist alongside the other RTLD_*

So why 0?  POSIX states wrt dlopen()[2]:

> If neither RTLD_GLOBAL nor RTLD_LOCAL are specified, then the default
> behavior is unspecified.

On Linux, RTLD_LOCAL is the default behaviour[3], and hence is defined
as 0[4], therefore I have done the same here.

Patch attached.  Since this doesn't actually do anything, I wasn't sure
if I should bump CYGWIN_VERSION_API_MINOR for this or not; I can
certainly do so before committing if desired.
