RCLOL_FILTER_HOST_ENV=1 makes exec-guest.py drop host session metadata
(WAYLAND_DISPLAY, XDG_SESSION_*, XDG_CURRENT_DESKTOP, GNOME/KDE/GDM,
systemd, SSH agent, terminal, toolkit, Flatpak/Snap/AppImage, exported
shell functions) and set SHELL to the guest's /bin/zsh. It is off by
default; RCLOL_KEEP_HOST_ENV lists names to keep anyway.

Unlike the denylist in #61, the filter runs after the launcher sets its
GPU tuning, keeps everything Darling and the host graphics and audio
libraries read (DISPLAY, XAUTHORITY, XDG_RUNTIME_DIR and the XDG base
directories, D-Bus, PulseAudio/PipeWire/ALSA, DRI_PRIME, MESA_*, __GL_*,
__NV_*, VK_*, LD_PRELOAD for gamemoderun, LD_LIBRARY_PATH), and lives in
one place instead of three.

tests/test_exec_guest.py runs in CI; the launcher check also verifies
that MESA_NO_ERROR=1 and __GL_THREADED_OPTIMIZATIONS=0 reach the guest
with the filter on.

Split from #61.
