flint declares unused dependency on python310

[ryandesign (Ryan Carsten Schmidt)]

The flint port declares a depenency on port:python310 however the configure phase output says:

-- Found PythonInterp: /usr/bin/python (found version "2.7.18") 

which makes me think python310 is not being used for anything.

I do not remember now if I got a failure without Python, but CMakeLists has the following:

find_package(GMP REQUIRED)
find_package(MPFR REQUIRED)
if (WITH_NTL)
    find_package(NTL REQUIRED)
endif()
find_package(PythonInterp REQUIRED)

16. S. Since it is often the case that undeclared dependency does not lead to a failure locally (script still finds everything needed), but causes failures on build bots, I might have added Python on basis of CMakeLists.

flint: ensure usage of correct Python

Fixes #65648
Fixes #66004

No revbump since port either builds correctly or not at all.
