openssl issue on Linux side

Here is the link to the forum: https://forum.subspace.network/t/error-while-loading-shared-libraries-libssl-so-1-1-cannot-open-shared-object-file-no-such-file-or-directory/447/4

Quick summary: because of the openssl dependency not being packed into the application, some of the openssl libraries in our user's machine may create some inconsistencies due to their version being different.

To fix it, we will embed the openssl library into the executable itself.

After we introduce attohttpc dependency on the frontend side with updater feature, this issue might have re-emerged. I just checked and confirmed unfortunately it is the case.
We may use vendored openssl for now until a better option comes in the future for resolving this. I'll submit a PR soon
