Setting the value of PARTITIONLIST in a sub-shell is scoped to the
sub-shell, it will not change the value of the variable in the parent
shell.
In other words:
#!/bin/sh
FOOBAR=
(FOOBAR=foo)
echo FOOBAR=$FOOBAR
gives the output:
FOOBAR=
As a consequence, PARTITIONLIST being empty, there are no part_*
modules embedded in the boot<platform>.efi binary. This is clearly a
regression, introduced in 7b36f5b0ad.
Somehow, Debian doesn't seem to be impacted. Kali Linux is impacted, but
only under very special conditions, leading to this bug report:

This commit fixes it, by setting the PARTITIONLIST variable first, and
then using it where needs be. As a consequence it greatly simplifies the
next part of the code, as we can just use a heredoc to create the grub
config.
