Rebuilding Xen with XSM support

Let's rebuild the Xen hypervisor and tools on the system with XSM support:

Clean up the previous build by running the make clean command inside the build directory (xen-4.13.1 in our example):

```
$ cd xen
```
Launch the Xen configuration using make menuconfig:
```
$ make menuconfig
```

Navigate to the XSM setting and enable the XSM-related parameters:

Common Features --->
  [*] Xen Security Modules support
  [*]   FLux Advanced Security Kernel support
  [*]     Compile Xen with a built-in FLAS security
