The attached is the revised patch.  In order to bind
`python-shell-interpreter' consistently, new macros
`python-tests-with-shell-interpreter' and
`python-tests-with-temp-buffer-with-shell-interpreter' were
introduced.  The patch is larger because some of the indentations have
been changed by using new macros.  I have fixed
`python-shell-interpreter' was not bound correctly in some ERTs, so
you might find new ERTs that fail with Python 2 on Mac.

Same as before, it would be helpful if you could try each of the
following on Mac.

1. Set EMACS_PYTHON_INTERPRETER environment variable to "python" and
   run ERTs.  The expectation is that the 7 ERTs that previously
   resulted in errors will be skipped.
2. Change the order of the interpreters in
   `python-tests-get-shell-interpreter' to  "python" "python3"
   "python2" and run ERTs.  The expectation is that the 7 ERTs that
   previously failed will succeed.

Another change is the behavior when the interpreter specified in
EMACS_PYTHON_INTERPRETER is not found.  In the current master, ERTs
are skipped if the interpreter specified by EMACS_PYTHON_INTERPRETER
is not found.  This is because although
`python-tests-get-shell-interpreter' raises an error, `skip-unless'
ignores it.

However, if the interpreter specified by EMACS_PYTHON_INTERPRETER is
not found, it is likely that EMACS_PYTHON_INTERPRETER is incorrectly
configured, and I would prefer to let it fail rather than let it be
skipped.  If it is better to be skipped, it would be better to have
`python-tests-get-shell-interpreter' return nil without raising an
error.  I would like to hear Lin's and others opinions on this matter.
