dev-python/hypothesis: bump to 3.6.0, eapi bump, fixed dependencies

A new version was released that removes the dev-python/uncompyle6 dep
introduced in 3.5.3. This also means that the KEYWORDS and pypy3 support
that were removed in eea41c4ca5bcd27af35f3276459567b91e4a34e7 can be
reintroduced. Also 3.4.2 no longer needs to be kept in the tree.

This package has a dependency on python being built with sqlite support.
It isn't obvious and only shows when other packages (like cryptography)
use certain modules of the library.
