Some wic images need this command. Since it is part of coreutils, it doesn't 
really
cost anything to have in HOSTTOOLS and it avoids signifiant build dependencies 
on
coreutils-native.

[necessary for building Linux kernel >= 6.11 with CONFIG_KALLSYMS, c.f.

The Linux kernel in its 6.11 release or later, with KALLSYMS config
enabled, will now fail to build because truncate host tools is
required, c.f.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1472464c6248575bf2d01c7f076b94704bb32c95

but the kernel recipe doesn't depend on coreutils-native, which is too
big of a dependency for what it brings according to Richard (for the
original patch destined to wic) and Bruce (as discussed over mailing
list for the linux-yocto recipe).

Let's backport a patch that was implemented for something else (wic)
from styhead/master as truncate is pretty much guaranteed to be present
on the host with hopefully no compatibility issues between
implementation.

Marked as RFC because it's a "big" change and I don't want the ML to
just gloss over it without questioning it :)

Note: I'm currently NOT building that kernel in my layer, but it'll come
at some point next year, though I did hit this issue when doing a very
quick test with a local tree.

Any feedback on that patch?

Cheers,
Quentin
