[PATCH 2/3] libc-package.bbclass: Only extract wanted files in prep_locale_tree()

[Peter Kjellerstedt <peter.kjellerstedt@axis.com>]

prep_locale_tree() predates the usrmerge DISTRO_FEATURE, which meant it
was not prepared for the case when ${base_libdir} == ${libdir}. This
lead to it extracting files and directories where it shouldn't.
