Use correct library reference for libfishhook.a in RCTWebSocket (#19579)

Summary:
This uses the reference for `libfishhook.a` from the Products, rather than
the reference from the Frameworks group.

This fixes the build for the new Xcode build system, on both Xcode 9 and
Xcode 10.

Fixes #19569

- Using Xcode 10:
	- Open `RNTester/RNTester.xcodeproj`
	- Build RNTester, noting build errors
- Using Xcode 9:
	- Open `RNTester/RNTester.xcodeproj`
	- Switch to using new build system in `File > Project Settings > Build System`, selecting `New Build System (Preview)`
	- Build RNTester, noting build errors
