crypto: upgrade pbkdf2 without digest to an error

Commit a1163582 added a deprecation warning when pbkdf2 was called without an
explicit `digest` argument. This was because the default digest is `sha1`,
which is not-recommended from a security point of view. This upgrades it
to a runtime error when `digest` is undefined per the plan discussed in
the original issue.
