Fixes: make test
Fixes QA test

Even if correctly implemented, this test did not work off-line. The
“example.com” domain is now “localhost” so it works even if no DNS is
configured on the system.
Fixes naming

Renames a definition originally imported from libhpack. Since it’s part
of libchula now, it should follow its naming convention.
Fixes CI's source analisys tool

This script still included a few references to libhpack.
Fixes TracisCI integration

Removes one of the —exclude parameters. There is no longer a
libchula/test directory in the source code tree.
