iommufd: Add a selftest
Cover the essential functionality of the iommufd with a directed test from
userspace. This aims to achieve reasonable functional coverage using the
in-kernel self test framework.
A second test does a failure injection sweep of the success paths to study
error unwind behaviors.
This allows achieving high coverage of the corner cases in pages.c.
The selftest requires CONFIG_IOMMUFD_TEST to be enabled, and several huge
pages which may require:
echo 4 > /proc/sys/vm/nr_hugepages
