[OE-core] [PATCH 2/3] image.bbclass: respect PACKAGE_NO_GCONV

[kai.kang at windriver.com]

From: Kai Kang <kai.kang at windriver.com>

It installs locale-base-* packages according to var IMAGE_LINGUAS.
Packages locale-base-* are split in libc-package.bbclass if variable
PACKAGE_NO_GCONV is not set. When none of ditro features libc-charsets
libc-locales and libc-locale-code is set, PACKAGE_NO_GCONV is set. Then
no locale-base-* is created and fails to create image.

Clear IMAGE_LINGUAS in such situation.
