feat(zkvmLib): Add the ability to override dependencies

Allows you to add `overrideVendorCargoPackage` and
`overrideVendorGitCheckout` to args, which allow the overriding of
vendored dependencies, as is implemented in crane.lib.

The respective attribute must be added to commonArgs (i.e. to both
`buildDepsOnly` and `buildPackage` args).
