init: load usb modules for devices using USB keyboard

Browse Source 
Some (out of tree) servers require use of a USB keyboard, and need
the USB kernel modules loaded prior to checking for keypress to enter
a recovery console. Since loading the modules affects the value in PRC5
and can cause issues putting a LUKS key in TPM, guard the loading of the
USB modules with CONFIG_USB_KEYBOARD and remove the unguarded call from
gui-init.

This should resolve issues #603 and #674.
