Fix names of Gentoo packages

[saraedum]

Gentoo renamed some build tools in late 2023. We update the names here to fix the broken CI runs for Gentoo (that happen e.g. for cypari2.)

📝 Checklist

• The title is concise, informative, and self-explanatory.
• The description explains in detail what this PR is about.
• I have linked a relevant issue or discussion. (Offline discussion at SageDays, i.e., cypari builds are broken.)
• I have created tests covering the changes. (There's already plenty of Gentoo CI in our setup that fails without this.)
• I have updated the documentation accordingly. Nothing to do there.

@fchapoton I am waiting to see if the Gentoo CI manages to install make.

[fchapoton]

maybe this specific CI needs to be triggered manually ?

LGTM w.r.t. the package names (checked on a real gentoo box). If something in CI needs fixing then it could be done in a followup.
