This creates a trait that different architectures can implement to
support running Linux VMs.
In the implementation on X86 we remove some error and return errors
from lower-level modules as appropriate. These modules now implement
the Error trait so we can get meaningful descriptions without an extra
error from the calling function. This still keeps all the ifdefs in
linux.rs for now until we have another implementation to use for ARM.
