Enable building with -DOPENSSL_NO_DEPRECATED.

If you didn't enable deprecated code, there were missing err.h and
bn.h includes.  This commit allows building with or without deprecated
code.

This was not derived from an OpenSSL commit.  However, they recently
enabled OPENSSL_NO_DEPRECATED in git and fixed these header problems
in a different way.

Verified with clang that this only changes line numbers in the generated
asm.
