tint: Add USB support

Enable the USB during the initialization of tint. Without it USB
keyboards don't work, which makes this payload pointless on
systems where a PS/2 keyboard port isn't available.

Based on I98f0ccdb19d6b195572941cf87ce3221f57db7c5 (tint and
nvramcui: enable USB, update tint to 0.04+nmu1 with changes) [1]
