[OE-core] [warrior][ 40/50] glibc-locale: Fix build error with PACKAGE_NO_GCONV = "1"

[Armin Kuster]

From: Jason Wessel <jason.wessel at windriver.com>

When the PACKAGE_NO_GCONV is set to 1 an empty directory is left behind from the do_install rule:

=====
ERROR: glibc-locale-2.29-r0 do_package: QA Issue: glibc-locale: Files/directories were installed but not shipped in any package:
  /usr/lib
  /usr/lib/locale
Please set FILES such that these items are packaged. Alternatively if they are unneeded, avoid installing them or delete them within do_install.
glibc-locale: 2 installed and not shipped files. [installed-vs-shipped]
ERROR: glibc-locale-2.29-r0 do_package: Fatal QA errors found, failing task.
=====

The simple fix is to prune the empty directory.
