bug: rover is built on centos 7 but... can't run on centos 7??

[EverlastingBugstopper]

if you try to install rover on centos 7, you'll get an error telling you that you can't because Rover needs glibc 2.18.

$ npx -p @apollo/rover rover supergraph compose
This operating system needs glibc >= 2.18, but only has 2.17 installed.
Downloading musl binary that does not include `rover supergraph compose`.

error: This version of Rover does not support this command.
        This is likely an issue with your current version of `glibc`. Try running `ldd --version`, and if the version >= 2.18, we suggest installing the Rover binary built for `x86_64-unknown-linux-gnu

this is a bald faced lie! we build rover's binaries on centos 7! what gives?

turns out, once we moved from ubuntu 16 to centos 7 we didn't need to require version 2.18, only 2.17. we added nice error handling so folks with glibc under our required version would safely download the musl version (which unfortunately doesn't include supergraph compose because it relies on deno_core which still can't be built on musl. however, for folks with version 2.17 this "helpful" behavior becomes not so helpful because our prebuilt binaries would work, but our installer scripts don't think it will.

This is all quite confusing and should be fixed by lowering the required glibc version from 2.18 to 2.17.

thanks to @theJC from Indeed for the report!
