Functions keyctl_restrict() and keyctl_dh_compute_kdf_alloc() are
nodefined. Their inclusion in version.lds causes clang/llvm LTO
optimizations to fail with error messages similar to

    error: version script assignment of KEYUTILS_1.7 to symbol
    keyctl_restrict failed: symbol not defined

This patch fixes the issue by removing the symbol names from
version.lds.

Fixes Gentoo bug 914637 (https://bugs.gentoo.org/914637)
