After a discussion in #debian-python, it appeared to make sense to
package this and patch it so its where() function returns the location
where Debian is already providing CA certificates. This will be easier
than having to patch every python package that depends on certifi.
If you do that please be sure to make it clear in the package
description what the Debian version of the package returns (the proposed
description in the ITP suggests that the package will return the list of
certs from python-certifi upstream).
