"/usr/lib/nss" is specific to Debian and its derivatives
such as Ubuntu.

On other Linux distributions, libsoftokn3.so and
libfreebl3.so are on the default shared library search path,
so you don't need to use full pathnames.

Hardcoding the list of NSS shared libraries that need to
be preloaded is fine by me.
