bootloader: remove dangling grubenv links
The rhel8.2 .qcow2 images have moved from a single xfs partition into an EFI style layout with separate /boot/efi partition. This means the root partition has /boot/grub2/grubenv as a symlink to ../efi/EFI/redhat/grubenv, which is dangling when we are running the bootloader element as /boot/efi is blank. grub-install tries to call rename() in the process of re-writing this file, which fails and bails out dib. Remove this symlink if it exists Change-Id: I5591144a3617dbae148b0c5d2a6a404942ffcd4e Parital-Bug: #1893029 Redhat-Bug: https://bugzilla.redhat.com/show_bug.cgi?id=1871669
