Strings in |MapFileParser| may contain concated thin archive paths like
"path/to/lib.a(../../path/to/object.o)". Normpath treats it as a path
and resolves second .. by removing the "lib.a(.." part. It breaks thin
archives processing, resulting in exceptions up the stack in |archive|
on calls to "rindex('(')".

Solution: thin archive paths do already get their paths normalized
later in |ar.CreateThinObjectPath|. So just skip them at this point.
