Fix tmpdir with standalone test strategy

If the tmpdir wasn't below the execroot, Bazel would crash and print a stack
trace.

Also, the test was incorrect because the EOF wasn't quoted, so it was actually
just executing "echo TEST_TMPDIR=/path/to/tmpdir" which (surprise surprise)
matched TEST_TMPDIR=/path/to/tmpdir.

Finally, the test was _also_ incorrect because it was using the cached test
result for the second case, since changing the tmpdir doesn't invalidate the
test result. So it not only was comparing a constant string to a constant
string, but it wasn't even re-evaluating the constant string.
