Bug#1005825: hatchling: please make the build reproducible

Hi,

Whilst working on the Reproducible Builds effort [0] we noticed that
hatchling could not be built reproducibly.

This is because it included the checksums of (unshipped) .pyc files in
the 'RECORD' file. A patch is attached that strips them out; this change
is analogous to a similar conditional later in the wheel.py file.
