We can say "You must install git on your machine", but IMHO
"the kernel must be managed by git" is a too strong assumption
because snapshots are delivers as a tarball (e.g. https://www.kernel.org/)
I could be wrong, but that is my intent (as in the commit description).

If tar's --exclude-vcs-ignores option had worked correctly,
I would not have written such a gitignore parser by myself.
When tar implements --exclude-vcs-ignores correctly,
I am happy to remove this silly tool.
(In turn, tar will end up with a similar gitignore parser as git, though.)
