Each invocation of userfaultfd for "anon" and "shmem" was taking about 6.5 sec to run, contributing to an overall run time of about 22 sec for run_vmtests.sh.
Reduce the size and bounce input values to the userfaultfd invocation within run_vmtests.sh, enough to get each invocation down to about 1.0 sec. This should still provide a reasonable smoke test, while staying within a nominal time budget of around 1 second or so per test. And this brings the overall running time of run_vmtests.sh down to 11 second.
