target-arm: do not set do_interrupt handlers for ARM and AArch64 user modes
User mode emulation should never get interrupts and thus should not
use the system emulation exception handler function. Remove the reference,
and '#ifndef USER_MODE_ONLY' the function itself as well, so that we can add
system mode only functionality to it.
