REG-TESTS: decompression: add basic decompression test

For now only basic HTTP decompression with a small payload is tested,
because TCP decompression is not trivial to test with VTEST, and a HTTP
decompression test with a big payload may eventually come later, provided
it is not too slow.

However, both request and response gzip decompression is tested. Other
compression methods are not tested because it is not the intend of
this test to check the decompression library itself, only haproxy
behavior.
