[U-Boot] [PATCH v2] tools/mxsimage: Support building with LibreSSL

The mxsimage utility fails to compile against LibreSSL because LibreSSL
says it is OpenSSL 2.0, but it does not support the complete OpenSSL 1.1
interface.

LibreSSL defines OPENSSL_VERSION_NUMBER with 0x20000000L and therefor
claims to have an API compatible with OpenSSL 2.0, but it does not
implement OPENSSL_zalloc() and some other functions in its most recent
version. OpenSSL implements this function since version 1.1.0.

This commit will activate the compatibility code meant for
OpenSSL < 1.1.0 also for all versions of LibreSSL, if some version of
LibreSSL will support these functions in the future the version check
should be adapted.
