[roll] Roll fuchsia [ffx][target] Improve error message.

Add a custom error message when no default target is specified and no
targets are available.

Also add the `target_errors_lib_test` to the build graph so we can run
them in CQ.

Before:
```
❯ ffx target list
No devices found.

❯ ffx repository server start
Switching log file to "/usr/local/google/home/$USER/.local/share/Fuchsia/ffx/cache/logs/repo_devhost.log"
Target specification "unspecified" was not found. Use `ffx target list` to list known targets, and use a different matcher.
```

After:
```
❯ ffx target list
No devices found.

❯ ffx repository server start
Switching log file to "/usr/local/google/home/$USER/.local/share/Fuchsia/ffx/cache/logs/repo_devhost.log"
No devices/emulators found. Please ensure the device you want to use is connected and reachable, or an emulator is started.
```
