Cygwin: uname: allow to specify external release info
When creating regular Cygwin test releases we need a way to
automate unambiguous version information based on the output
of `git describe'. Allow to inject a release string via a
preprocessor macro CYGPORT__RELEASE_INFO. Change the default
release info to recognize a local, non-distro build.
