Gregory Nutt 90eed5c8f8 tools/zds/zdsar.c: Use shorter, relative paths
This tools needs to CD to directory holding the library because it requires that the library be in the current working directory when objects are inserted.  Previously, the tool did this by creating an absolute path to the object file itself.  So instead of the object file being in the current directory and the library in a directory at an absolute path, this tool used an abolte path to the object file with the library in the current directory.

For the most part, that worked fine.  However, in the apps directory the object file names are greatly extended in length.  In the object file name was extended to a full absolute path and these huge file names were were exceeding some internal limit within the ZDS-II librarian.  But useing shorter, relative paths, we were able to avoid hitting this limit and the entire build completed correctly.
