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

[changbin . du]

From: Changbin Du <changbin...@intel.com>

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.

Fixes: 4366d57af1 ("x86/build: Factor out fdimage/isoimage generation commands 
to standalone script")
