Subject: [PATCH] mptcp: MPTCP_KUNIT_TESTS should depend on MPTCP instead of selecting it

MPTCP_KUNIT_TESTS selects MPTCP, thus enabling an optional feature the
user may not want to enable. Fix this by making the test depend on
MPTCP instead.

I think the initial intension was to select MPTCP to have an easy way to
enable all KUnit tests. We imitated what was and is still done in
fs/ext4/Kconfig.

But it probably makes sense to depend on MPTCP instead of selecting it.
So that's fine for me. But then please also send a patch to ext4
maintainer to do the same there.

Thanks, good point. I didn't notice, as I did have ext4 enabled anyway.
Will send a patch for ext4. Looks like ext4 and MPTCP where the only
test modules selecting their dependencies.
