python3: match packages by pattern in version check override

The override lists every python3 package by name, so it has to change
whenever the package set does, and it cannot be used as is on branches
that build a different set, like libpython3-3.13 and python3-email on
openwrt-25.12.

Check the interpreter, python3-dev and libpython3-X.Y against the
version, and accept the standard library modules and -src packages by
pattern, since they ship no executables. python3-dev now gets a real
check through python3-config and patchlevel.h, because python3-config
prints no version.
