add3prf.py: Update value for crates.io identifier
According to go/thirdparty/metadata#identifier
> The identifier field is used to enable this functionality. The type
> field should correspond to one of OSV's defined ecosystems or one of the
> google internal types. Select the identifier type which matches where
> the package was obtained before importing to Piper. The value should be
> the name of the package as defined within that ecosystem - see the
> examples below.
The OSV's defined ecosystem is here:
https://ossf.github.io/osv-schema/#affectedpackage-field
For "crates.io" the table says the name field should be the crate name.
