[OE-core] [PATCH] bitbake.conf: add git-lfs to HOSTTOOLS_NONFATAL

[Martin Jansa]

Would it make sense to at least as temporary work around add a flag saying
that git-lfs does or doesn't exist in HOSTTOOLS after it being added
to HOSTTOOLS_NONFATAL and then let those few recipes which already use
git-lfs to check this flag and fail early with meaningful error message
about git-lfs? It can be in a bbclass so that all recipes can easily share
it and it can be later changed to add dependency on git-lfs-native (if
there is one later).

Only issue is that people will forget to inherit this bbclass in their
recipes if it just happen to work.

Adding it to some subdirectory inside HOSTTOOLS which is added to PATH only
when the bbclass is inherited might be a bit too much for just a work
around :/.
