In 21a597c <https://reviews.llvm.org/rG21a597c31cb8ad03e18a293c73ecd7c498387ef8>, we fixed a module loading issue by using the new
`argparse.BooleanOptionalAction`. However, this is only available
starting python 3.9 and causes test failures on bots that don't fulfill
this requirement.

To address that, this patch replaces the use of `BooleanOptionalAction`
by a pair of 2 opposite `store` actions pointing to the same destination
variable.
