<telega-paths-patch>: Rename to...
<patch-sources>: ... this.  Also don't patch paths to subdirs.
Remove the snippet, that would push contrib to the load path.
<server-suite-patch>: Rename to...
<patch-test-suite>: ... this.
<emacs-install>: Also install etc.
<emacs-bytecomp-contrib, telega-install-contrib, telega-install-data>: Removed
phases.
