glibc: add '/usr/lib{32,64}/*/' to ld.so.conf

Note:

We should migrate to a more modular approach here, moving to package
based configuration in '/etc/ld.so.conf.d/$pkg.conf' and including all
dedicated conf files in a generic main 'ld.so.conf' like this:

include /etc/ld.so.conf.d/*.conf

base/glibc/glibc.conf
