[PATCH] scripts: allow checkpatch and get_maintainer in sparse checkouts

[CaoRuichuang]

checkpatch.pl and get_maintainer.pl currently reject sparse checkouts because top_of_kernel_tree() insists on top-level directories such as arch/, drivers/ and fs/ being present in the working tree.

That unnecessarily blocks common patch preparation workflows using partial clones or sparse checkouts, even when the files needed by these tools are present.

Relax the tree check to require only the top-level files and directories these scripts actually need so they continue to recognize full trees while also working from sparse checkouts.
