CryptoPkg: OpensslLib: reintroduce EFIAPI for ERR_add_error_data()

Git commit f93f78ea70 (SVN r17633), with subject "CryptoPkg: Update
openssl patch file from 0.9.8zf to 1.0.2c", replaced the file

  CryptoPkg/Library/OpensslLib/EDKII_openssl-0.9.8zf.patch

with

  CryptoPkg/Library/OpensslLib/EDKII_openssl-1.0.2c.patch

In the process, two hunks were lost that used to add EFIAPI to the
declaration of the variadic function ERR_add_error_data().

The VA_START() macro, from "MdePkg/Include/Base.h", expands to an
EFIAPI-dependent implementation when

  !defined(__CC_ARM) && (!defined(__GNUC__) ||
                         defined(NO_BUILTIN_VA_FUNCS))

Under such circumstances, the va_start() macro invocation in
ERR_add_error_data() -- which is translated to VA_START() by
"CryptoPkg/Include/OpenSslSupport.h" -- results in EFIAPI-dependent code,
but callers of the function pass the arguments incorrectly, because the
declaration doesn't state EFIAPI.

This leads to crashes when ERR_add_error_vdata(), called by
ERR_add_error_data(), tries to access the arguments forwarded to it.

Restore the missing hunk from before SVN r17633.
