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

[Hauke Mehrtens]

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.
