Fix build if build dir is outside source dir
tests/debugger/host/host.c was moved from tests/debugger/oegdb/host/host.c.
The relative #include must be adapted to this.
#include <openenclave/internal/error.h>
#include <openenclave/internal/tests.h>
#include <string.h>
-#include "../../../../host/sgx/enclave.h"
+#include "../../../host/sgx/enclave.h"
// The following variables are initialized so that the assertions below will
// fail by default. The test expects the debugger to update the values
