packaging: don't crash building wix with python3.6 and earlier
`capture_output` was added in 3.7. I was tempted to just check and abort in
build.py, since Windows doesn't have the Linux problem where some distros only
ship an older python. But this is in a library that could be used elsewhere in
the future.
