Fixes#1382
System memory gets fragmented over time and repeated hugepage
allocations fail, giving us intermittent failures on CI. Linux
allocates those pages only when requested hugepage count is bigger
than current hugepage count, so in order to prevent any additional
allocations just stick to a single count all the time.
autotest_common.sh already exports HUGEMEM=8G for Linux systems
and 2G for BSD ones. `setup.sh reset` doesn't touch the hugepages,
so practically only the first `setup.sh` will allocate memory now.
The two setup.sh calls are run with sudo, so they need
HUGEMEM="$HUGEMEM" to work.
