Script to install via Docker

[eraserhd]

• Fix for install-dev.sh
• Script for installing via Docker

This allows me to install the last release from NixOS, which can't use the
dynamically linked binaries. It's also nice that it doesn't install adb
on my system.

Note that this only gets as far as the second "waiting for reboot..." but the system is usable at that point.

The changes in #284 may make it able to build and install on NixOS without needing docker.

@eraserhd Do you still need to use a container to build and install rayhunter on NixOS now that we use musl & static linking for all targets, including the serial binary? Please re-open this if you do, but from our testing it shouldn't be necessary to wrap the install scripts in a container anymore.

Additionally, we're replacing the scripts with a statically linked Rust installer in #291 -- feel free to test that out if you like.
