[master] deb, rpm: reduce uses of "cd", "popd", "pushd"

[thaJeztah]

For make commands, we can just pass the directory through "-C", and for "install" we can pass the full path of the source.

There's some remaining uses for targets that build through a script or using "go build", which may still require changing.

Hope that DESTDIR works here 🤔

Looks like it worked;

Complete!
