x86/build: Don't verify mtools configuration file for isoimage

If mtools.conf is not generated before, 'make isoimage' could complain:

  Kernel: arch/x86/boot/bzImage is ready  (#597)
    GENIMAGE arch/x86/boot/image.iso
   *** Missing file: arch/x86/boot/mtools.conf
  arch/x86/boot/Makefile:144: recipe for target 'isoimage' failed

mtools.conf is not used for isoimage generation, so do not check it.
