Subject: [PATCH] Introduce TDESKTOP_DISABLE_LEGACY_TGVOIP

Originally from Alt Linux[0], OpenBSD has so far adapted the removal of
tgvoip in the official net/tdesktop build.

tgcalls provides everything needed for calls;  audio/video/desktop
sharing calls have been working fine across different operating systems
and telegram desktop/mobile versions without problems.
