Drop udev dependency for frecon-lite

This patch expands the existing frecon-lite concept that is currently
only managed by ebuilds (and the DBUS=0 command line flag) to be known
within the frecon Makefiles. Code that is different between the two
binaries is split into separate files with _full.c/_lite.c suffix.

Also decouple frecon-lite from udev so that we can drop another big
dependency from the recovery initramfs. Instead frecon-lite will simply
listen to all /dev/input/eventX nodes that exist on startup. We don't
really care about hotplugging for recovery, and the extra power
consumption from listening to irrelevant inputs doesn't really matter
for that use case.

BUG=chromium:984814
TEST=Ran recovery on Kevin, confirmed I could still switch VTs with
Ctrl+Alt+F2.
