Not necessarily correct, no. 
cargo install does not use the lockfile, see 
https://doc.rust-lang.org/cargo/commands/cargo-install.html#dealing-with-the-lockfile
The cargo-build-system also doesn't use it.
The crate importer also doesn't use it :)

First, I'd try to make sure that guix build rust-tonic works.

This page helped me a lot in getting started: 
https://guix.gnu.org/manual/en/html_node/Debugging-Build-Failures.html

I tried to reproduce this locally (import and build), building rust-tonic works 
fine for me.
Funnily enough, I'm running into a completely different error, related to 
https://github.com/hyperium/tonic/blob/408f46d5f2e1a25547831eb4b064bdeaf3868979/tonic-build/src/lib.rs#L47-L60
