run test suite without dashed git-commands in PATH

Only put bin-wrappers in the PATH (not GIT_EXEC_PATH), to emulate the
default installed user environment, and ensure all the programs run
correctly in such an environment.  This is now the default, although
it can be overridden with a --with-dashes test option when running
tests.

 You can also set the GIT_TEST_INSTALLED environment variable to
 the bindir of an existing git installation to test that installation.
 You still need to have built this git sandbox, from which various
