selftest/timerns: fix clang build failures for abs() calls
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.
