patch 9.0.0253: a symlink to an autoload script results in two entriesv9.0.0253

Problem:    A symlink to an autoload script results in two entries in the list
            of scripts, items expected in one are actually in the other.
Solution:   Have one script item refer to the actually sourced one.
            (closes #10960)
