Wrap all vboot utilities with futility.firmware-spring-3833.Bfactory-spring-3842.B

This moves all the old userspace utilities generated by vboot_reference into
a subdirectory not in $PATH, and replaces them with symlinks to a single
executable named 'futility'. At the moment that utility just execs the
original utilities (optionally logging that fact first).

Ultimately, the old utilities will be subsumed into a single binary instead
of multiple separate executables.

There is a matching CL needed to make the recovery image creation work.

BUG=chromium-os:37062
BRANCH=none
CQ-DEPEND=CL:44864
TEST=auto

To test, build everything, test everything. It should work as before in all
cases. I have built normal images, test images, factory installers, recovery
images; they all seem to work.

I've run trybots on daisy-paladin link-paladin lumpy-paladin and alex-paladin.
