Be more selective about copying libcrypto symbols into legacy.so

Some private libcrypto symbols are also included in legacy.so.
Unfortunately this included some files with "RUN_ONCE" functions and
global data. This doesn't get properly cleaned up when OpenSSL exits.
Therefore we are more selective about the symbols we include in legacy.so.

Fixes #13560
