Subject: [PATCH] Parenthesize Py<type>_Check() in ifs

In C, if expressions should be parenthesized.
PyLong_Check, PyUnicode_Check etc. happened to expand to a parenthesized
expression before, but that's not API to rely on.

Since Python 3.9.0a4 it needs to be parenthesized explicitly.

Fixes https://gitlab.gnome.org/GNOME/libxml2/issues/149
