py-numpy16: no need to use versioned_dependencies

This is for 3.8 only.

Log message:
py-numpy16: remove support for Python 2

AFAICT this is not needed any longer;
its Python 3.8 support is still needed though.

py-numpy16: allow python 3.8 for blender-lts

Log message:
py37-reduce: Drop 37 from PYTHON_VERSIONS_ACCEPTED

Drop 37 from PYTHON_VERSIONS_ACCEPTED for all but
py-backports.cached-property (which exists only for 37, and I'm
guessing it will build fine and not cause trouble).

This follows the new plan of "37 is all but removed, with the
lang/python37 package remaining, but py37-foo are not built by
default" compromise to avoid problems from the current state of
massive py37-foo build failures while stopping short of outright
removal.

Log message:
py-numpy16: allow Python 3.7 as well (un-break builds)

Now that Python 3.7 is also directed here for builds, include it in
PYTHON_VERSIONS_ACCEPTED.
