uname -s is wrong (you will get the same answer for two different cygwin
installations on the same underlying Windows, but different answers across
different Windows versions).  But uname -r is reliable.

Coreutils is part of every cygwin installation, as is every other package
in the Base category (for example, findutils, tar, bash...).  In other
words, there are some programs so essential to a unix-y environment that
you can count on them being present.

But that said, all coreutils' uname(1) does is call uname(2).  So emacs
can reliably use uname(2) (provided by cygwin1.dll) rather than wasting a
fork to call uname(1).
