locales are not set in buildchroot

[Alexander Smirnov <asmirnov@ilbers.de>]

Hi all,

I've noticed that locales are now broken again in buildchroot, dpkg 
produces tons of garbage in current 'next':

Log data follows:
| DEBUG: Executing shell function do_build
| /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

| 	LANG = (unset)
|     are supported and installed on your system.
| perl: warning: Falling back to the standard locale ("C").
| /bin/bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

| 	LANGUAGE = (unset),
| 	LC_ALL = "en_US.UTF-8",

I guess this caused by migration to debootstrap, please consider to fix 
this in next series.
