feat(3p/telega): Pin tdlib version used for telega

Browse source 
Recent channel updates have caused some issues for telega.el, mostly
because the version of tdlib (the C++ library for Telegram) and the
Emacs package are out of sync.

This overrides the version used in the Emacs package to a "known good"
commit. It would be useful to change the tdlib derivation in nixpkgs
to make this version mismatch a hard build error.
