linux: punch holes in guest memory for file mappings

Rather than manually adding special handling for regions where we want
to put --file-backed-mapping mappings, we can just iterate over those
regions before constructing the GuestMemory object so that there will be
no conflicts/overlaps between RAM and file-backed mappings.

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.
