Raspberry Pi Camera

• Use raspi-config to enable camera
• Update udev rules (I did this for both vchiq and vcsm, not sure if both necessary)
• Revert 2 commits
• Rebuild userland for 64bit
• ln -s vcsm /dev/vcsm-cma -- highly unclear why this is needed

Pro-tip: when building a Docker image that includes picamera, set this env:

ENV READTHEDOCS=True

It informs picamera not to scream that it can't find a camera when building (presumably b/c it must be built as part of RTD generation). It builds fine; why it needs the hardware during build time I have no idea.
