Make 20-grub.install to exit if there is no machine ID set

Browse source 
The kernel-install plugins are called with an environment variable named
$KERNEL_INSTALL_MACHINE_ID, which is set to the machine ID read from the
/etc/machine-id file. If the file doesn't exist or is empty, the variable
is empty and $BOOT_DIR_ABS is set to a temporary directory that's removed
after all the plugins exit.

So if $KERNEL_INSTALL_MACHINE_ID is not set, just exit the script since
installing a kernel BootLoaderSpec fragment won't be possible anyways.
