Intel 945: Select LAPIC_MONOTONIC_TIMER for X86EMU_DEBUG_TIMINGS

X86EMU_DEBUG_TIMING is needed for producing i915tool
  compatible output. So add its dependencies to the
  i945’s Kconfig in order to be able to use X86EMU_DEBUG_TIMINGS,
  which depends on HAVE_MONOTONIC_TIMER which
  LAPIC_MONOTONIC_TIMER provides/selects.

Note that UDELAY_LAPIC is already selected by the Intel CPU.
