Telegram's own Linux runtime checks whether the installed .desktop file's
Exec matches its actual binary path, and silently writes a private copy to
~/.local/share/applications with a randomized name whenever it doesn't.
Our desktop entry pointed at the /usr/bin/telegram-desktop symlink, which
never matched /opt/telegram-desktop/Telegram, so Telegram regenerated a
shadow launcher on every start, producing a second, unmatched icon.
Exec/TryExec now point directly at the installed binary so Telegram's own
check finds a match. Bumped release and updated the checksum for the
changed desktop file.
Repackages the official static tsetup.7.0.5.tar.xz Linux build for
amd64, keeping the upstream org.telegram.desktop desktop-id and
TelegramDesktop WM class.
