Daniel P. Berrangé 85b983485b tests/vm: custom openbsd partitioning to increase /home space
The openbsd image is 20GB in size, but the automatic partitioning
done by the installer leaves /home with a mere ~3.5 GB of space,
wasting free space across many other partitions that are not
used by our build process:

openbsd$ df
Filesystem  512-blocks      Used     Avail Capacity  Mounted on
/dev/sd0a      1229692    213592    954616    18%    /
/dev/sd0k      7672220        40   7288572     0%    /home
/dev/sd0d      1736604        24   1649752     0%    /tmp
/dev/sd0f      4847676   2505124   2100172    54%    /usr
/dev/sd0g      1326684    555656    704696    44%    /usr/X11R6
/dev/sd0h      4845436   1445932   3157236    31%    /usr/local
/dev/sd0j     10898972         4  10354020     0%    /usr/obj
/dev/sd0i      3343644         4   3176460     0%    /usr/src
/dev/sd0e      2601212     19840   2451312     1%    /var

This change tells the installer todo custom partitioning with
4 GB on /, 256 MB swap, and the remaining ~15GB for /home

openbsd$ df
Filesystem  512-blocks      Used     Avail Capacity  Mounted on
/dev/sd0a      7932412   4740204   2795588    63%    /
/dev/sd0d     32164636        40  30556368     0%    /home

This will avoid ENOSPC failures when tests that need to create
big files (disk images) run in parallel.
