makefile: get setup tools out of the equation

Without these two flags, the new install does not overwrite the older one.
Impressive to see that in 2023 this is still broken.

For the record, `setup.py --help install` says:

  --old-and-unmanageable               Try not to use this!
  --single-version-externally-managed  used by system package builders to
                                       create 'flat' eggs

let's look at the contents of the caches

the reason we're doing this is to make sure our serialization works the same
way on all platforms, see https://bz.mercurial-scm.org/show_bug.cgi?id=6354

we don't need to check sqlite caches
