Skip hanging tests on Cygwin (bug#65325)

* test/lisp/server-tests.el (server-tests/can-create-frames-p):
Define to be nil on Cygwin unless Emacs has at least one of the
features gfilenotify, dbus, or threads.  This causes three tests
to be skipped.

* test/src/keyboard-tests.el (keyboard-unread-command-events):
Skip on Cygwin unless Emacs has at least one of the features
gfilenotify, dbus, or threads.
