Roll Fuchsia SDK to 893404234442cf13abbc4e22ed996839ff5b1338

Updates clang toolchain_libs path to 7.0.0.

Includes https://fuchsia-review.googlesource.com/c/zircon/+/115121
which should fix component builds crashes.

Also renames calls from zx_time_get() to zx_clock_get() per recent
Fuchsia syscall change.
