Hermes fails to compile on Ubuntu 22.04 due to __fxstat

[lukemartinlogan]

Hermes won't compile on Ubuntu 22.04. Either __fxstat was removed, they changed the headers, or they require some additional macro to enable it. We should figure out what APIs need to be intercepted to do stat* functions. This may result in requiring kernel-specific builds of Hermes for portability.
