Fix tests
Fixes #35 (closed) .
This is just a part of #40
I removed a whole package (http13client) which was the golang's http client copied and pasted and which had a failing test. The only reason I found for vendoring it is this part of changelog:
* [r=chipaca] vendor the go 1.3 development net/http bits which
properly/better support timeouts for requests; see _using.txt and
Makefile for the recipe in http13client
Since version 1.3, at the time of speaking, is a super old version, I believe it is better to use the one provided by the standard library.
I'd like to see this compiling on CI since when building on pdk, in test execution, I get a file not found
error about testing.key not being copied into buildsources
folder. Did not have this problem in my other MR
Thank you
