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.
libbrotli, libbz2, libfontconfig, libffi, libglib2 and hicolor-icon-theme
don't exist as such in ALT's repos. Verified real names against this
machine's apt-cache: libbrotlicommon/libbrotlidec, bzlib, libfontconfig1,
libffi8, glib2, icon-theme-hicolor.
tsetup.tar.xz bakes in uid/gid 1000 from Telegram's release tooling;
the sandboxed builder can't chown to it, so the build failed with
"Невозможно изменить владельца". --no-same-owner/--no-same-permissions
matches the pineconemc package's handling of the same issue.
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.
