[igt-dev] [PATCH i-g-t] tests/tools_test: Use readlink() properly

[igt-dev] [PATCH i-g-t] tests/tools_test: Use readlink() properly

[Arkadiusz Hiler]

Turns out that `readlink()` does not NULL-terminate the string and since
it resides on the stack we may end up with some junk:

  `/proc/self/exe point to /opt/igt/libexec/igt-gpu-tools/tools_test7<CD>\t<8A>^?`

That in turn confuses `dirname()` and we end up doing `chdir("/")`,
which explain the sporadic failures of this test where it was not able
to locate the tools.

Let's zero out the variable first and allow `readlink()` to write at
most `sizeof()-1` bytes to it, so it is always properly terminated.

My word, it is even mentioned in the manpage.
