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.

Add some fixes for BLS parsing logic and also make 20-grub.install script
to query the relative path of the kernel and initramfs images, so BLS can
also work when /boot is not a mount point or is a btrfs subvolume.
Also pull some build fixes.

- Use version field to sort BLS entries if id field isn't defined
- Add version field to BLS fragments generated by 20-grub.install

If MAKEDEBUG=yes in /etc/sysconfig/kernel, then a debug menu entry should
be created. So for BLS, a debug configuration file has to be created that
contains debug kernel command line parameters.

Install a 20-grubby.install and 90-loaderentry.install kernel-install
scripts in /etc/kernel/install.d so these have higher precedence than
the ones installed in /usr/lib/kernel/install.d by the systemd pkg.
If GRUB 2 pkg isn't installed, then the systemd scripts are executed
on kernel installation and removal.
