vim: ensure python3 is linked dynamically on Linux

Currently, the python3 interpreter is linked statically on Linux.
However, the embedded interpreter still needs the Python runtime to
function, and this runtime is provided by the linked Python formula.
The interpreter thus breaks whenever Python is updated, since it can no
longer find the runtime.

Let's try to fix this by making sure the interpreter is linked
dynamically instead.

See discussion at #113036.
