DAOS-723 Fault: Allow Fault Injection framework to be compiled out (#402

)

The fault injection framework in CART is a developer/test focused feature. The
feature should not be present in production systems so it is not built in by
default. It can be enabled by specifying --with-fault-injection on the scons
build line.
