[build][alln] Fix zircon library dependency

This CL relies on [1] being submitted first to fuchsia.git.
It updates library references to libzircon.so to the appropriate
target, to allow moving the sysroot generation to the Fuchsia
build. See [1] for more details.

Bug: 60613
Testing: Should not change the build.
