Bug#1143818: rust-ruma-common: unsatisfiable autopkgtest dependency.

Package: rust-ruma-common
Version: 0.14.1+ds-16
Severity: serious

https://ci.debian.net/data/autopkgtest/testing/arm64/r/rust-ruma-common/74110409/log.gz

> 523s E: Unable to satisfy dependencies. Reached two conflicting assignments:
> 524s    1. satisfy:command-line:arm64=1 is selected for install
> 524s    2. satisfy:command-line:arm64 Depends librust-ruma-appservice-dev
> 524s       but none of the choices are installable:
> 524s       [no choices]
> 524s rust-ruma-appservice-api:default FAIL badpkg

Looking at recent commits, I'm guessing this is a typo and was intended
to be librust-ruma-appservice-api-dev
