linuxPackages.bbswitch: 0.8 -> unstable-2021-11-29

Switch to the development branch, as it's basically stable at
this point, and pinch Arch's 5.18 compat patch.

Also remove existing patches:
- PR 102 was rejected upstream, the actual issue is
  https://github.com/Bumblebee-Project/bbswitch/issues/112,
  and can be worked around via acpi_osi=Linux
- PR 196 is applied upstream.

(cherry picked from commit e1c59eaf85)
