mkarchroot: Don't let the environment affect pacstrap (sans proxy settings).
A previous iteration of this change (libretools commit d7dcce53396d) simply inserted `env -i` to clear the environment. However, that lead to it ignoring proxy settings, which some users had problems with: https://labs.parabola.nu/issues/487: > To fix other bugs, the pacstrap environment is blank, which also > means that the proxy settings are blank. So (in libretools commit d17d1d82349f), I changed it to use `declare -x` to inspect the environment, and create a version of it only consisting of variables ending with "_proxy" (case-insensitive). I honestly don't remember what "other bugs" prompted me to clear the environment in the first place.
