luacheck rightfully complains that i is unused in the show-module-options
loop at the end (it was used for some debugging in the process).

We've added a new pager module that's compiled in, so declare that as an
acceptable global.

r346652:
Complain and exit the script if the 'make install' phase fails.  Also,
there is no need to install any debug files.

r346653:
The zfs module has grown a dependency on zcl_nfs4.ko, so copy it into all
the test images.

r346654:
For the geli-gpt-zfs test images, both bios and uefi flavors, add a dummy
ufs partition as p2, and put the zfs partition at p3, to test the ability
of the zfs probe code to find a zfs pool on something other than the first
partition.

Use userboot.so from the test directory if possible, fall back to .OBJDIR.
This avoids a problem that we've had since userboot coexistence was added,
where userboot.so alone no longer exists in the .OBJDIR but is instead just
a link installed later.
Update lualo

either.

'efi' rather than as '!239'.
