difftool: avoid double slashes in symlink targets

Browse source 
When we add tests for symlinks in "git difftool --dir-diff" it's easier
to check the target path if we don't have to worry about double slashes
separating directories.  Remove the trailing slash (if present) from
$workdir before creating the symlinks in order to avoid this.
