[OE-core] [PATCH v2] sdk: Fix SDKIMAGE_LINGUAS handling

[Richard Weinberger]

Currently SDKIMAGE_LINGUAS is broken for any inputs except "all".
In the non-"all" case, each enabled language package is installed via
pm.install("nativesdk-glibc-binary-localedata-%s.utf-8" % lang)
This will throw a python exception since pm.install() expects a list of
strings and not a string.

Fix the problem by constructing a list.
That way it is now also possible to call the package installer just
once.
