Fix build configs to make Thrift stresstest work

Summary:
Fix a few issues in Thrift stresstest and its dependencies, mostly related to build configs:

* Make folly liburing dependencies consistent between fbcode and xplat, otherwise uring is disabled.
* Build the stresstest `Server` target for the target instead of the host platform.
* Enable the FBCODE platform for binaries for dependency remapping to work.
* Replace `fbcode_exported_deps` with `exported_deps` for targets that are now consistent between fbcode and xplat.
