base-platform: Add the openssl 1.0 runtime
We recently upgraded the main OpenSSL to 1.1, but kept a compatibility, runtime-only OpenSSL 1.0.
This was necessary both to be able to build OpenSSH in the base sdk, and to avoid breaking apps which had been built against OpenSSL 1.0: these apps would move to OpenSSL 1.1 next time they were rebuilt, but until then they need 1.0.
However, in those commits I forgot to actually add the OpenSSL 1.0 runtime to the base platform, which means it was only in the Sdk, breaking compatibility for apps.
This commit fixes this.
@jjardon did you finish importing freedesktop-sdk-18.08.10 into Flathub? If so, my apologies for missing this and breaking apps.
