git-annex test from standalone speedup

Browse source 
Avoid git-annex test being very slow when run from within the standalone
linux tarball or OSX app.

It may not really be necessary to add to PATH the directory where the
git-annex binary resides, but it can't hurt. Most places where the test
suite or git-annex run git-annex, they use programPath, so won't need
a modified PATH. But I'm not sure if that's always the case.

I have fixed the problem I identified, which was due to git-annex test adding
the cwd to PATH, which caused it to run git-annex.linux/git, so runshell
was being run repeatedly and unncessarily.
Now it will run git-annex.linux/bin/git and avoid the repeated runshell
overhead, so will be about as fast as git-annex not run from the standalone
tarball.
