[Buildroot] [git commit] util-linux: explicitly use /usr/{bin, sbin, lib}, with merged usr

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=099c2ceaa8adfcdcbbaf039000e1fe26a33a6165
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Prevent the installation from attempting to move shared libraries from
${usrlib_execdir} to ${libdir} if both paths are the same, which leads
to error messages like this:

  mv: '$(TARGET_DIR)/usr/lib/libfoo.so.1' and '$(TARGET_DIR)/lib/libfoo.so.1' are the same file

That error is not fatal but let's avoid possible future problems.
