Add wifi station support

- Adds wpa_supplicant.
- Adds wifi network selection screen, using wpa_supplicant's new DBus API.
- Keep /settings mounted rw, so wpa_supplicant can store its config there.
- Switch to dhcpcd as DHCP client instead of busybox's udhcpc
  Handles interface hot-plugging better.
- Enable Raspberry Pi wifi dongle in kernel configuration.
- Add firmware files for wifi dongle.
- Disable user-space hotplug helper in kernel configuration
  Newer kernels can fetch firmware files from /lib/firmware without help.
- Raise "wait until NOOBS initializes" timeout to 8 seconds.
