Update to littleproxy >= 1.1.2 to fix multiple (SSL) issues

[livin]

Currently betamax depends on littleproxy-1.1.0-beta2.

Unfortunately this version doesn't include multiple fixes which was done in 1.1.0, 1.1.1 and 1.1.2.

Please take a look at release notes.

Currently I am can't use betamax due to one of the issue which is SNI issue.

I tried to replace littleproxy-1.1.0-beta2 with littleproxy-1.1.2 setup - but it looks like betamax is not compatible with it due to not implementing some newly signed methods.

The update is highly needed and appreciated.
