add helper functions to get kernel path by kernel release and the path of current running kernel
grubby --info=kernel-path or --add-kernel=kernel-path accepts a kernel
path (e.g. /boot/vmlinuz-5.14.14-200.fc34.x86_64) instead of kernel release
(e.g 5.14.14-200.fc34.x86_64). So we need to know the kernel path given
a kernel release. Although for Fedora/RHEL, the kernel path is
"/boot/vmlinuz-<KERNEL_RELEASE>", a path kernel could also be
/boot/<machine-id>/<KERNEL_RELEASE>/vmlinuz. So the most reliable way to
find the kernel path given a kernel release is to use "grubby --info".
For osbuild, a kernel path may not yet exist but it's valid for
"grubby --update-kernel=KERNEL_PATH". For example, "grubby -info" may
output something as follows,
index=0
kernel="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64"
args="ro no_timer_check net.ifnames=0 console=tty1 console=ttyS0,115200n8"
root="UUID=76a22bf4-f153-4541-b6c7-0332c0dfaeac"
initrd="/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/initramfs-5.15.10-100.fc34.x86_64.img"
There is no need to check if path like
/var/cache/osbuild-worker/osbuild-store/tmp/tmp2prywdy5object/tree/boot/vmlinuz-5.15.10-100.fc34.x86_64
physically exists.
Note these helper functions doesn't support CoreOS/Atomic/Silverblue
since grubby isn't used by them.
