test/setup: Perform custom alloc based on hugepages' size not quantity

Browse Source 
512 and 1024 number of hugpages is not a sensible value in case 1G
hugepages are in use. Instead of setting fixed number of hugepages,
determine it safely based on the default size and allocate 1GB for
node0, 2GB for node1 (if present).

Fixes: #1954
