[PATCH] Fix wg-tool regex parsing for non en_US locale

[Arti Zirk]

On systems that have the default locale set to anything other than en_US
or C will be unable to use wg-quick because regex rules use to make sure
that the input interface name is a valid will fail. Forcing locale
inside the script to C seems to fix that.
