BUG/MINOR: pattern: Fix pattern lookup for map with opt@ prefix

When we look for a map file reference, the file@ prefix is removed because
if may be omitted. The same is true with opt@ prefix. However this case was
not properly performed in pat_ref_lookup(). Let's do so.

This patch must be backported as far as 3.0.
