fix various issues

[mrpalide]

Did you run make format && make check? Yes

Fixes #1779 #1769 #1753 #1694

Changes:

• Fix issues on Windows and Mac installer based on v1.3.20-rc1
• Fix start and stop issue on proxy/vpn (include ctrl+c command)
• Fix --timeout flag on start proxy/vpn
• Fix --http flag to skysocks to serve httpproxy beside socks5

How to test this PR:
You can run visor and trying to start/stop proxy and vpn by these commands:

• skywire cli proxy start --timeout 30 --http :1010
• skywire cli vpn start --timeout 20
• check ctrl+c command during running apps
• For fixing installers, I'll push v1.3.20-rc2 after merging this PR.

We shouldn't auto-start the http proxy. Especially in instances where I need to test a lot of proxy servers, the http proxy running just takes up another port needlessly
