glean_parser depends on `iso8601`, but only on Python <= 3.6.
Add the `iso8601` hash to our frozen dependency hash list accordingly.

At the moment installing Python packages with native code is done by calling
`pip install <package>` and does not enforce any SHA hash for installed
dependencies, nor does it enforce a specific version to be installed.
This commit adds `requirements.in` and `requirements.txt` files for native
packages and changes these packages to be installed by running `pip install`
and passing the requirements file for the package. This allows us to pin the
SHA of the various dependencies. The `.txt` files are generated using
`pip-compile`.
We also add the new requirements files to the sparse profile for `mach`.
