Libguestfs - Apr 2022 - [supermin PATCH 0/1] Fix for missing /lib/modules.

When running guestfish without a /lib/modules directory, the following
error message appears:

supermin: ext2: populating from base image
supermin: ext2: copying files from host filesystem
supermin: ext2: copying kernel modules
supermin: error: lstat: No such file or directory: /lib/modules
libguestfs: error: /usr/bin/supermin exited with error status 1, see debug
messages above

Even though I set the environment variable $SUPERMIN_MODULES, supermin
expects to find the /lib/modules directory.

Note: I tried to use ext2fs_mkdir, but an error message that I didn't know
how to fix:

File "ext2fs.ml", line 29, characters 24-93:
29 | external ext2fs_mkdir : t -> string -> string -> int ->
int-> int -> int-> int -> int -> unit =
"supermin_ext2fs_mkdir"
                            
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: An external function with more than 5 arguments requires a second stub
function

Even when supplied with $SUPERMIN_MODULES, supermin tries to access
/lib/modules. This directory does not exist by default in all the
environments.
