Improve the description of Cygwin ldd utility to give a bit more detail

Also add a security warning (modelled after the one in the Linux manpage)
that it may end up executing the file it is applied to.

<command>ldd</command> invokes the Windows loader on the file specified,
then uses the Windows debugging interface to report DLLs loaded, and
(for executables) to attempt to stop execution before the entrypoint.
Thus, you should never use ldd on an untrusted file.
