image_types_wic: fix expansion error

Variable WKS_SEARCH_PATH was not fully expanded when used directly
in this expression:
    WKS_FULL_PATH = "${@wks_search('${WKS_FILES}'.split(), '${WKS_SEARCH_PATH}') or ''}"

This caused expansion error: bb.data_smart.ExpansionError:
Failure expanding variable WKS_FULL_PATH, .... which triggered exception
SyntaxError: invalid syntax (WKS_FULL_PATH, line 1)

Calling d.getVar instead of directly referencing variables
should fix the issue.
