I'd suggest using "ext4: add kunit test for decoding extended
timestamps" as the one-line summary, and we probably don't need
anything else.

Should we perhaps just call the cofnig "EXT4_KUNIT_TESTS"?  Right now
the only thing we test is timestamp encoding/decoding, but later on
we'll be adding other other ext4 uninit tests --- and more ext4
encoding tests is not neceesarily where I would start, since the rest
are actually quite straightforward.

(The next set of uninit tests I'm interested in is the ext4's
extent_status tree, since that requires minimal amounts of test
mocks.)

So we might as well make the config name more general to begin with.
