* sys/fuchsia: update zx_clock_get.
zx_clock_get was deprecated and replaced by zx_clock_get_new. In a
recent CL[0], they replaced the zx_clock_get by zx_clock_get_new and
moved all client. This commit updates syzkaller to use the new function.

* run make extract && make generate
* sys/fuchsia: update all syscalls.
This commit modifies all the existing syscalls definitions to match more
closely the documentation in the Fuchsia repo.
* run make extract && make generate
* 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
