First, I was following what GIT_TEST_INSTALLED does (it points to bindir,
not to git binary).  Second, I had half of idea to also change paths to
static files... but they are not used anyway, at least not currently
(no check for links).

Anyway we can support both situations, slightly similarly to how
GIT_TRACE can have different kinds of values.
