Add a new test flag SPDK_RUN_NON_ROOT forcing some of the
SPDK applications to run as an unprivileged user. For now
we implement it in nvmf tests. If enabled, nvmf_tgt will
run as the user who invoked `sudo ./autotest.sh`.
Running SPDK as non-root has two major prerequisites right now:
* there must be an IOMMU in the system in order to use PCI devices
* DPDK version must be either < 18.05 or >= 19.08-rc1
