Passing a file as a command argument in string form assumes that
run_command has the current subdir as its cwd, but Meson's documentation
*explicitly* calls this out as undefined and wrong to use.
Indeed, muon has a different implementation that uses a different cwd,
and this argument cannot be found. Instead, passing a files() object
means that it's the job of meson itself to verify the file exists, then
pass it to the run_command in some format that guarantees it is a valid
path reference.
Kubevirt is currently technically based on KVM (but not xen yet[1]).
The systemd-detect-virt command, used to differentiate the current
virtualization environment, works fine on x86 relying on CPUID, while
fails to get the correct value (none instead of kvm) on aarch64.
Let's fix this by adding a new 'vendor[KubeVirt] = kvm' classification
considering the sys_vendor is always KubeVirt.

machine: Add APIs CopyTo[Machine]WithFlags + CopyFrom[Machine]WithFlags
- Same API to those without `WithFlags` (except this can take flags)
- Initially, only a flag to allow replacing a file if it already exists
- Add a test that asserts that copy_tree on an existing file will fail without COPY_REPLACE
- Add a test that asserts that copy_tree with COPY_MERGE and COPY_REPLACE on an existing directory will overwrite files that already exist.
- Refactor: Move HardlinkContext to header file
- Refactor: Create `fd_copy_tree_generic` which isolates the functionality to check stat type and appropriately copy.
- Refactor: Create `fd_copy_leaf` which handles copying leaf nodes of a file tree.
The other variables are owned by the boot menu (i.e. sd-boot), we only
fill those in if it didn't do so for us (to support cases where our stub
kernel is directly invoked by UEFI). But StubInfo is genuinely about the
stub, hence let's simplify things and unconditionally set it from the
stub.
THis will be useful in a later commit, when we add more stuff to the
common exit path. But even without that, it's a nice simplification,
removing redundant lines.
When running on images you don't want to modify the /tmp
directory even if it's writable, and often it will just
be read-only. Set PrivateTmp=yes.

This reverts commit e4de58c823.
If mkdir() fails and the path does exist, then the later mount
command fails anyway. Hence, it is not necessary to fail here.
Fixes#24120.
