libsodium: don't update config.sub, congig.guess from git.savannah.gnu.org (#635)

As of August 30, 2024, `git.savannah.gnu.org` returned a
502 error when trying to download `config.guess` and `config.sub`.
For example, attempting to download [this link](https://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD)
returned a 502 error. As a result, all scripts, workflows, etc.,
that relied on getting fresh versions of `config.{sub,guess}`
from `git.savannah.gnu.org` are failing. To prevent this, we
disabled updating to the fresh versions of these scripts.
