crypto/bio: fix build on UEFI

When compiling openssl for tianocore compiling abs_val() and pow_10()
fails with the following error because SSE support is disabled:

   crypto/bio/bio_print.c:587:46: error: SSE register return with SSE disabled

Fix that by using EFIAPI calling convention when compiling for UEFI.
