[OE-Core][PATCH v11][master-next 5/5] opkg: set locale from system environment variables

["Piotr Łobacz" <p.lobacz@welotec.com>]

A C program inherits its locale environment variables when it starts up.
This happens automatically. However, these variables do not automatically
control the locale used by the library functions, because ISO C says that
all programs start by default in the standard ‘C’ locale.

Fixes warnings:
Warning when reading ar archive header: Pathname can't be converted from UTF-8 to current locale. (errno=84)
