Nguyễn Thái Ngọc Duy efd71f8913 t/helper: add an empty test-tool program
This will become an umbrella program that absorbs most [1] t/helper
programs in. By having a single executable binary we reduce disk usage
(libgit.a is replicated by every t/helper program) and shorten link
time a bit.

Running "make --jobs=1; du -sh t/helper" with ccache fully populated,
it takes 27 seconds and 277MB at the beginning of this series, 17
seconds and 42MB at the end.

[1] There are a couple programs that will not become part of
    test-tool: test-line-buffer and test-svn-fe have extra
    dependencies and test-fake-ssh's program name has to be a single
    word for some ssh tests.
