Debian does not ship a 'mkisofs' symlink to genisoimage. All modern
distros ship genisoimage, so just use that directly. That requires
renaming the 'genisoimage' function. Also neaten up the 'for' loop
while I'm in here.

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.

This change suppresses the 'dd' output and adds the '-quiet' parameter
to mkisofs tool. It also removes the 'Using ...' messages, as none of the
messages matter to the user normally.
"make V=1" can still be used for a more verbose build.
The new build messages are now a streamlined set of:
$ make isoimage

It avoids the following warning triggered by newer versions of mkisofs:
-input-charset not specified, using utf-8 (detected in locale settings)

Recently I failed to build isoimage target, because the path of isolinux.bin
changed to /usr/xxx/ISOLINUX/isolinux.bin, as well as ldlinux.c32 which
changed to /usr/xxx/syslinux/modules/bios/ldlinux.c32.
This patch improves the file search logic:
- Show a error message instead of silent fail.
- Add above new paths.

The build messages for fdimage/isoimage generation are pretty unstructured,
just the raw shell command blocks are printed.
Emit shortened messages similar to existing kbuild messages, and move
the Makefile commands into a separate shell script - which is much
easier to handle.
This patch factors out the commands used for fdimage/isoimage generation
from arch/x86/boot/Makefile to a new script arch/x86/boot/genimage.sh.
Then it adds the new kbuild command 'genimage' which invokes the new script.
All fdimages/isoimage files are now generated by a call to 'genimage' with
different parameters.
Now 'make isoimage' becomes:
