build user has no env LANG & LC_TYPE

[wwwutz]

when sudo -u build the envs LANG and LC_CTYPE are unset.

This forces util-linux's col command to fail on UTF-8 input.

our system defaults are

LANG=C
LC_CTYPE=en_US.UTF-8

setting them in the build scipts does fix the issue.

Most environment variables are unset by sudo. The switches below exist to change that behavior.

1. -E, --preserve-env
2. --preserve-env=list

That's not the point. I don't want the sudo process to inherit ANY $ENV my process has.

That said: PATH is set, LANG not.
