Squelch locale warnings in Debian package maintainer scripts 

Bug-Debian: http://bugs.debian.org/508764

The system locales are rather frequently out of sync with the C library
during package upgrades, causing a huge amount of useless Perl locale
warnings. Squelch them when running package maintainer scripts, detected
by the DPKG_RUNNING_VERSION environment variable.

Any real locale problem will show up after the system upgrade too, and
the warning will be triggered normally again at that point.

The message tells about some problem in your system's locale support,
and you should investigate what the problem is.
=item DPKG_RUNNING_VERSION
On Debian systems, if the DPKG_RUNNING_VERSION environment variable is
set (to any value), the locale failure warnings will be suppressed just
like with a zero PERL_BADLANG setting. This is done to avoid floods
of spurious warnings during system upgrades.
See L<http://bugs.debian.org/508764>.
