Subject: [PATCH] Fixes analysing a wild attribute to return Info

As per issue #4671:

erl_syntax_lib:analyze_attribute({attribute,17,mark,mark_1}).

returns {mark, {mark, mark_1}} due to the attribute being wrapped on
line 1320:

{A, analyze_attribute(A, Node)}

when what would be expected as per the documentation is:

{mark, mark1}

Returning *just* the Info from {_, Info} = analyze_wild_attribute(Node)
within analyze_attribute/2, this double wrapping does not occur, fixing
the original issue.
