elput: Fix support for setting keyboard led(s)

Small patch to update keyboard led(s) when caps, numlock, etc are
pressed. This patch adds some fields to internal (non-API exposed)
structures inside our private header (of a BETA-API library) and thus
should still be ok during freeze.

Fixes T5655

@fix
