modules: add failsafe module
The failsafe module adds a minimal web-interface which is intended to run on a very compact initramfs-based image intended only for flashing firmware onto a device. This can be used as part of an installation method or reside in a small partition on the device flash which can be booted in case the checksum-test of the main kernel or rootfs fails.
