The TAP specification requires that the output begins with a header line.
These headers lines are missing in the timens tests.
Print such a line.

selftest/timerns: fix clang build failures for abs() calls2024-07-05T19:21:48+00:00John Hubbardjhubbard@nvidia.com2024-07-04T02:52:47+00:00urn:sha1:f76f9bc616b7320df6789241ca7d26cedcf03cf3
When building with clang, via:
make LLVM=1 -C tools/testing/selftests
...clang warns about mismatches between the expected and required
integer length being supplied to abs(3).
Fix this by using the correct variant of abs(3): labs(3) or llabs(3), in
these cases.
