do not use the -u (update) flag when copying kernel images and inird from /boot to the ESPs: * the ESPs are formatted with vfat, which has a 2 second precision for mtime (`linux/fs/fat/misc.c` - `fat_truncate_time`) * cp -u compares the mtimes of source (kernel image in /boot not on vfat) and destination - leading to the copy always being carried out, if the source files remain the same (and do not happen to have a mtime exactly happening on a even second) as laid out in the bug-report - the case where this leads to an unbootable system is when a kernel-version is shipped twice (built with different tool-chains) - e.g. currently the 5.11 kernels in PVE 6 and PVE 7. tested the behavior of `cp -u` by running opensnopp-bpfcc and copying a file twice onto ext4 (opened only once) and on vfat (opened twice). additionally reproduced the issue (by dist-upgrading a PVE 6 VM to 7 with the pve-no-subscription repo) and verified this patch fixes it.
