[arch-projects] [namcap] [PATCH] Add py_mtime rule

[keenerd]

This is a patch inspired by
https://www.archlinux.org/todo/fix-bad-mtime-pycpyo-files-for-python-packages/

It checks packages with py/pyc/pyo files for time conflicts.  When a
py file is newer than a pyc/pyo python locks up a little while
figuring out what to do.

Sometime it is our fault for copying files in the wrong order or doing
a sed after the pyc was generated.  Sometimes it is upstream's fault;
many setup.py scripts copy them in the wrong order.

The test checks both the tar file and the mtree logs.  If there is a
time error in the tar file, it will affect every installation.  If the
error only appears in the mtree file, then the package will be fine
but there is a chance that you won't get as lucky the next time the
package is built.  The tar case generates an error and the mtree case
generates a warning.

My apologies for including the patch as an attachment.  I tried to
send this with 'git send-email' but every time Mailmain said "Message
rejected by filter rule match"
