toybox host binary: avoid ODR violations.

We were seeing crashes with both /lib/x86_64-linux-gnu/libcrypto.so.1.1
and our hermetic /home/enh_google_com/bin/../lib64/libcrypto-host.so in
the stack trace. Let's just take one of those (and preferably, "our
one"!)...

Bug: http://b/307849291
Test: `./toybox id` on an affected host
