nss: Fix tst-nss-files-alias-truncated for default --as-needed linking
Linking to the NSS module directly does not work if the linker defaults to --as-needed because it will remove the apparently unused DSO reference and not generate a DT_NEEDED entry. Use an explicit dlopen call, like in the other chroot tests involving NSS modules.
