python3-sepolicy: remove direct_url.json and its RECORD entry
The direct_url.json
file contains a reference to the requested origin URL of
the installed package, as specified in PEP610[1]. During Debian package
builds, the install origin is a temporary directory on the build host's
local filesystem (a file://
URI) - ephemeral, different between each build
of the package, and a cause of non-reproducibility for package builds.
This fix is modeled on a one-off fix for a different package in #982529. There is also a precedent[2] for dh-python to remove this file automatically, although at the time-of-writing that only applies to Python packages that use the 'flit' framework as their Python buildsystem.
