test-runner: allow booting directly into a shell

Browse Source 
It is sometimes valuable to just boot into a shell in order to manually
test functionality. Since test-runner already is setup to run a minimal
kernel with all the necessary requirements for hostapd/iwd it made
sense to allow the user to do this.

If -s,--shell is passed into test runner, no python tests will be run.
The hw.conf file is still used to setup IWD and hostapd so once booted
into the shell you can still (manually) run the test (e.g. via iwctl).

This also works when using USB/PCI passthrough. This makes testing
out different kernel version with real hardware much quicker than
using the host kernel.
