build-openssl.bat: keep OpenSSL 3 engine binaries

Prior to this change copying the OpenSSL 3 engine binaries failed
because 'engines-1_1' (OpenSSL 1.1.x folder name) was erroneously used
instead of 'engines-3'. The OpenSSL 3 builds would complete successfully
but without the engine binaries.

Closes https://github.com/curl/curl/pull/10542
