gnu: emacs-telega: Test Emacs environment on startup.

Print a more helpful error message when someone attempts to run Telega on an
incompatible Emacs (e.g a 32-bit Emacs without wide ints).

* gnu/packages/patches/emacs-telega-test-env.patch: New file.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/emacs-xyz.scm (emacs-telega)[source]: Use it.
