fuchsia: Update syzkaller to build with current Fuchsia API. (#543)

* fuchsia: Fix the `extractor` tool.

The include path in Zircon has changed; updated syz-extract/fuchsia.go
to include this, and re-ran extract to get updated *.const files.

* fuchsia: Update syzkaller to build with current Fuchsia API.

Fuchsia doesn't have a stable API right now, so alas, this will probably
continue to change until that's nailed down.

But, useful to get this up-to-date at least.

Relevant notes:
* zx_channel_call_finish and _retry aren't technically public; leave
them out until we have a less-cludgy way to expose them
* musl supports setjmp/longjmp but not _setjmp/_longjump
* remove some unsupported syscalls
* update the build invocation
