Andrew Chow f6f18eeaa8 guix: Zip needs to include all files with time as SOURCE_DATE_EPOCH
The zip for codesigned MacOS distribution needs to have all files have
the same timestamp. These files also need to be included in the zip as
zip is not automatically recursive. We use the same pattern for zip as
is done for the other zip files produced by guix.

# Although Guix _does_ set umask when building its own packages (in our case,
# this is all packages in manifest.scm), it does not set it for `guix
# environment`. It does make sense for at least `guix environment --container`
# to set umask, so if that change gets merged upstream and we bump the
# time-machine to a commit which includes the aforementioned change, we can
# remove this line.

# This line should be placed before any commands which creates files.
