HTTPClient: TLS handshake error (export)

[LinuxUserGD]

Godot version:
master (standard/mono version)

OS/device including version:
Antergos OS (Arch Linux)

Issue description:
I've made a project that downloads assets from github and streams it into godot using the ssl certificate from https://github.com/godotengine/godot/blob/master/thirdparty/certs/ca-certificates.crt .
While the game runs fine in the editor, after exporting it to the same platform I get the following error:

Steps to reproduce:

• download https://github.com/HugeGameArtGD/Solus-Stunts/archive/v5.0-beta.zip
• runs fine in editor, but download doesn't work in the exported game

I'm not sure but maybe the ca-certificates.crt file isn't packaged in the export. I'll try to rename it to .res .

Or try to add *.crt to the export filter
