The future toolchain did not build the sanitizers, so debug
executables did not link. Fix by not disabling the sanitizers.

Next Fedora will likely not have toxiproxy packaged [1]. Adapt
by installing it directly. To avoid changing the current toolchain,
add a ./install-dependencies --future option. This will allow us
to easily go back to the packages if the Fedora bug is fixed.

To avoid surprises when libstdc++, clang, or other components
in the toolchain introduce regressions, we introduce a "future
toolchain". This builds on the Fedora version under active
development, and the development branches of gcc and llvm.
The future toolchain is not intended to be frozen. Rather,
periodically we will build the future toolchain, then build
ScyllaDB and run its unit tests under that toolchain, then
discard it. Any problems will then have be be tracked down
by a developer and either reported to the source repository,
or fixed in ScyllaDB.
