Changed to 'tests-source-dir' following other plural uses of 'tests'.

They don't work.

You can't have a compile test in inet/ and one in sysdeps/unix/sysv/linux/
which adds to inet/ without breaking the source<->test mapping for the
inet/ test. I can document that.

It's a limitation of the simplicity of the static pattern
rule and my desire to keep the impact minimal on the build cost.
