Windows,bootstrapping: respect TMPDIR
Respect the user-defined TMPDIR, or use TMP or
TEMP on Windows. Since MSYS sets TMP and TEMP to
"/tmp" which is actually "<msysroot>/tmp" (e.g.
"c:\tools\msys64\tmp"), it is shorter than the
Windows-default TEMP directory.
This buys us a bit of headroom to not hit path
length limits while bootstrapping.
Fixes https://github.com/bazelbuild/bazel/issues/4536
