Fix require monkey-patching in electron build

Summary:
In D39311893 (094c5bdfdd) we started monkey-patching `require` to resolve global dependencies in the plugins. Apparently, patching `globalThis.require` did not work in the electron env. On my local machine it kept working because I had the experimental `flipper-server` feature enabled which embeds flipper-server into the electron build. In flipper-server we properly patch `require` via `Module.prototype.require` which affected the global require in electron.
With this fix we now properly patch require in electron via Module.prototype.require all the time

Changelog: Fix plugin loading with experimental flipper-server disabled
