nix: stop passing watchman socket to Nix builds
This passing of Watchman socket was implemented in order to avoid this:
```
Error: EMFILE: too many open files, watch
    at FSEvent.FSWatcher._handle.onchange (node:internal/fs/watchers:204:21)
Emitted 'error' event on NodeWatcher instance at:
    at NodeWatcher.checkedEmitError (/private/tmp/nix-build-status-mobile-build-nightly-android.drv-0/node_modules/sane/src/node_watcher.js:143:12)
    at FSWatcher.emit (node:events:527:28)
    at FSEvent.FSWatcher._handle.onchange (node:internal/fs/watchers:210:12) {
  errno: -24,
  syscall: 'watch',
  code: 'EMFILE',
  filename: null
}
```
Which is caused by `jest-haste-map` used by `metro` starting to watch
the filesystem for file changes, which is pointless when doing a
one-off build using Nix.

But by setting `CI=true` we can make `metro` not start this waching of
files in the first place, removing the need for use of Watchman entirely.

By entirely dropping use of Watchman we also fix the following issue:
```
[cli] unable to talk to your watchman on /tmp/tmp-status-mobile-ABC/jenkins-state/sock! (Permission denied)
```
Which happens on multi-user Nix installations becuase the user that the
Nix build is executed as is not the same as the user that starts
Watchman and creates the socket file.
