eglibc packaging: locale packaging configuration

eglibc packaging: locale packaging configuration

The PACKAGE_NO_GCONV var manipulations ware happening in the
eglibc-options.inc file, and the eglibc-locale recipe do not
see it. Moving that into the libc-package.bbclass which is
common to eglibc & eglibc-locale recipes.

This fixes bug: [YOCTO #2089]

This avoids this error for poky-tiny
