execve: Move KUnit tests to tests/ subdirectory

Move the exec KUnit tests into a separate directory to avoid polluting the local directory namespace. Additionally update MAINTAINERS for the new files and mark myself as Maintainer.

v1: https://lore.kernel.org/lkml/[email protected]/
v2: file suffix changed to _kunit instead of _test
I'll toss this into -next and send it to Linus before -rc1 closes.
