deps: Use a patched rn-fetch-blob to fix Android 14+ crash

This updates rn-fetch-blob to a version with one cherry-picked commit
atop the v0.11.2 we were previously using:
  zulip/rn-fetch-blob@e17b2a51c

The rn-fetch-blob package itself is no longer maintained:
  joltup/rn-fetch-blob#863

There's a fork that is maintained, `react-native-blob-util`:
  https://npmjs.com/package/react-native-blob-util

That fork addressed the Android 14 requirement to set an
explicit RECEIVER_EXPORTED flag (zulip#5903), merging a fix:
  RonRadtke/react-native-blob-util#303
  RonRadtke/react-native-blob-util#306

Our fix is cherry-picked from that one.

(If this app weren't a legacy codebase in maintenance mode, we'd take
the time to upgrade this dependency more generally, probably switching
to the react-native-blob-util fork.  As is, we'll skip that and use
the time to focus on completing the new Flutter app.)

Fixes: zulip#5903
