In various places both in t/t/s/v/Makefile as well as some of the test sources, we were referring to headers or directories using some fairly long relative paths. Since we have a working top_srcdir variable though, which refers to the root of the kernel tree, we can clean up all of these "up and over" relative paths, just relying on the single variable instead.
