To Reproduce
Steps to reproduce the behavior:

1. export LANG=hu_HU.UTF-8
2. export LC_MESSAGES=hu_HU.UTF-8
3. pkexec ls
4. It shows Authentication is needed to run `/usr/bin/ls' as the super user instead of Hitelesítés szükséges a(z) „/usr/bin/ls” futtatásához rendszergazdaként"

Expected behavior
The authentication message is in Hungarian.
