Set rlimit if virtio IOMMU or coIOMMU is used

vIOMMU will dynamically pin VM's memory and in the extreme case they
might pin the entire VM's memory. RLIMIT_MEMLOCK will control how
much memory can be pinned by the process. So set the RLIMIT_MEMLOCK
to be allow pinning the entire VM's memory in the extreme case.

BUG=b:188481989
TEST=Boot a VM with Network device pass through w/ coiommu, and perform
the iperf test.

crosvm - The Chrome OS Virtual Machine Monitor

crosvm is a virtual machine monitor (VMM) based on Linux’s KVM hypervisor, with a focus on simplicity, security, and speed. crosvm is intended to run Linux guests, originally as a security boundary for running native applications on the Chrome OS platform. Compared to QEMU, crosvm doesn’t emulate architectures or real hardware, instead concentrating on paravirtualized devices, such as the virtio standard.

crosvm is currently used to run Linux/Android guests on Chrome OS devices.
