Subject: [PATCH] fix(getinstdisk): use an Intel RSTe/VROC software RAID when
 no other disk is found

On a node whose OS disk is an Intel RSTe/VROC software RAID (/dev/md/Volume0_0
or /dev/md/Volume0), disk auto-detection finds nothing and getinstdisk falls
back to the hard-coded /dev/sda. Prefer the VROC volume over that default.

Only fires when no install disk was otherwise selected and the VROC device
actually exists, so it cannot mis-select over a real disk and has no effect on
non-VROC systems. The original commit hooked into a lenovobuild-specific M.2
detection block absent from master; adapted to master's fallback point.

Not lab-validated (no VROC hardware available).

Recovered from the unmerged lenovobuild branch (c6c70e5).
