[isar-cip-core][PATCH 1/5] squashfs-img: Cosmetic cleanups

[Jan Kiszka <jan.kiszka@siemens.com>]

From: Jan Kiszka <jan.kiszka@siemens.com>

SQUASHFS_EXCLUDE_DIRS is given a default value in this class, so the
'or ""' is redundant. Furthermore, remove the unneeded space from the
SQUASHFS_CREATION_ARGS default assignment as well as misleading comment
in front of its anonymous constructor function.
