Update zlib.py

[Caesurus]

according to https://tools.ietf.org/id/draft-levine-application-gzip-03.html#rfc.section.2 the mime-type application/zlib is also valid, and so should be handled by this plugin.

Shoot, I had meant to do two PRs, one for the zlib mime-type, and then another separate one for the linux kernel stuff, but silly me... I made the zlib change via the github web UI, and then when I cloned locally I forgot to branch off and kept working in master.

I have some changes i haven't pushed yet. and I'll incorporate your review comments as well. I'll As such, I'll convert this to draft for the time being. Sorry for the mixup :)

Ok, should be ok now. I went and compiled a kernel as small as i easily could (make tinyconfig) and made a bzImage for each compression supported in the kernel menuconfig. I checked those in as test data, so there is better coverage of the different compressions (and making sure the tools are actually installed correctly). I don't know how you feel about adding that many binary files to the repo. If it's frowned upon, I can remove a bunch.
