bootc install to-existing-root failed on aarch64 test #1975
Description
The failure comes from bootc commit 0a75768 or 0a75768, because commit 51dabaa passed.
efibootmgr needs write access to /sys/firmware/efi/efivars to modify EFI boot variables (like deleting boot entries with -B)
This PR is a simple fix, mount /sys as read-write.
