classes: image_types: quote variable assignment needed by dash

The change in commit 39fc503036
("classes: image_types: apply EXTRA_IMAGECMD:squashfs* in oe_mksquashfs()")
assigns $@ to a local variable without quoting it. While this works with
bash, it fails with dash. Here, only the first token of $@ is assigned
to the variable, and the reamining tokens are passed as arguments to the
"local" keyword.

Fix it by adding the missing quotes.
