feat: use manylinux-interpreters tool if present

[mayeut]

This will allow dropping some EOL (and maybe some none EOL) python interpreters in manylinux images which would allow to reduce its size (faster for a vast majority of user, a small slow-down for users of those interpreters).

Updates to keep tests times down are not here yet, this is just to get things started.

Small suggestion - Defaulting to true then changing to false seems a little odd, maybe this is more normal? Also, which manylinux-interpreters could be used? It even seems like you could make this one step by just suppressing the ensure call?

Suggested change

	has_manylinux_interpreters = True
	has_manylinux_interpreters = False

[henryiii]

Suggested change

	try:
	# use capture_output to keep quiet
	container.call(["manylinux-interpreters", "--help"], capture_output=True)
	except subprocess.CalledProcessError:
	has_manylinux_interpreters = False
	with contextlib.suppress(subprocess.CalledProcessError):
	# use capture_output to keep quiet
	container.call(["manylinux-interpreters", "--help"], capture_output=True)
	has_manylinux_interpreters = True

(also add contextlib import above)

The comments are minor, I'm also happy with this as is for now. I assume it's good to get in so that manylinux can eventually require it.

I'm happy as-is. Nice neat implementation thanks to the design of manylinux-interpreters :)
