In the case were someone removes the current kernel we do not can
"keep" it anymore. While this was obviously no issue for the
autoremoval logic, it is an issue for the pve-efiboot-tool refresh
command, which reuses this helper to see which kernels it needs to
keep on the ESP.
Without this a running kernel was never removed from the EFI System
Partitions if de-installed from a host, so if it sorted as newest one
it was then booted again, which naturally confuses users (it was just
removed!!). So to ensure that we cannot get such zombie kernels
ensure that only installed kernels are included in the list.

still not enough to make it fully work, as a previous fix (initrd entry removal
from /proc/cmdline) doesn't work with `mawk` AWK (the default) but only with
`gawk` as it uses GNU AWK extensions
