A previous change that added a flag around the fault injection mechanism broken the host userspace build. This patch fixes it by enabling the flag and adding the appropriate source file to the host Makefile JIRA NVGPU-1246 Change-Id: I060a04bdd28eaf5039fe1fb0d2ad6150d0a74455 Signed-off-by: Nicolas Benech <nbenech@nvidia.com> Reviewed-on: https://git-master.nvidia.com/r/2090906 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Alex Waterman <alexw@nvidia.com> Reviewed-by: mobile promotions <svcmobile_promotions@nvidia.com> Tested-by: mobile promotions <svcmobile_promotions@nvidia.com>
