bootstrap: Avoid needless sudo when pkgs are installed (#33281)

- Previously on fedora `./mach bootstrap` would always detect it needs to
  reinstall packages and require root permissions.
- use custom queryformat for `rpm -qa` to to just get the package name
  (e.g. `openssl-libs` instead of `openssl-libs-3.2.2-3.fc40.i686`
- Use a list to store the output result instead of one string
- Fedora (40) installs `zlib-ng` instead of `zlib` and `libjpeg-turbo` instead
  of `libjpeg`, meaning that `rpm` / dnf commands report `zlib` as not installed.
  Specifying the actually installed package avoids this problem.
