Hi,

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

This is because it:

  a) It embeds a RECORD file that contains non-deterministic filename
  contents. 99% sure this is being generated by build.py.

  b) The manpage is being generated incorrectly, and actually is a
  manual page depicting an error message:

    .TH TRACEBACK "1" "July 2020" "Traceback (most recent call last):" "User Commands"
    .SH NAME
    Traceback \- manual page for Traceback (most recent call last):
    .SH DESCRIPTION
    .SS "Traceback (most recent call last):"
    .IP
    File "debian/flit/usr/bin/flit", line 2, in <module>
    .IP
    from flit import main
    .PP
    ModuleNotFoundError: No module named 'flit'
    .IP
    File "debian/flit/usr/bin/flit", line 2, in <module>

Patch attached. For a), we simply delete this file and for b) we fix
the generation by setting the right/full PYTHONPATH.
