dbginfo.sh: collect config files of systemd-modules-load.service

Recent multipath-tools can depend on this.
https://github.com/opensvc/multipath-tools/commit/a1eabea75e8e0f6072f2b655cae25ec473b006c5
("multipathd.service: drop ExecStartPre for loading dm-multipath")
https://github.com/opensvc/multipath-tools/commit/92f0893ac1f0c9daf7eef8753e6bd9730bcce4c6
("multipath-tools: install modules-load.d/multipath.conf")

This can now also include /usr/lib/modules-load.d/s390-pkey.conf
Complements v2.8.0 commit
dffd41943e ("pkey: Support autoloading kernel pkey module").
