Set neutral locale (C) when running package manager or version commands

[afbjorklund]

Some of the output is locale-specific, which might affect the parsing (or scraping)

So it should probably run the commands with LC_ALL=C in the environment

Noticed by user with Arch Linux with a german locale, in containers/podman#22148.

    package: /usr/bin/pasta ist in passt 2024_03_20.71dd405-1 enthalten

Better to use LC_ALL=C.UTF-8 which is something that most Linux distributions should be shipping with these days.

The package names and versions are ASCII anyway, so the encoding doesn't really matter (only the language used)
