folly/coro/Coroutine.h: avoid a -Wdeprecated-this-capture warning

Summary:
Avoid build failure with xcode 15.4.
While -Wdeprecated-experimental-coroutine was deleted in upstream llvm17,
`__APPLE__` llvm reflects that deletion in their version llvm16.
Updating to xcode 16.0.0 RC1 makes this change unnecessary.
