Fix -d option processing

When converting the path specified for -d to absolute path, an extra '/'
is added, e.g. if '/mypath' is specified, TMPBASE will be '//mypath'.
Some testcases fail because of this, e.g. chdir01A fails with:

chdir01     1  TFAIL  :  symlink(object, symbolic) was succesful.
mkdir(object, 0700) was successful
chdir(2) returned successfully, but getcwd(3) indicated new current
working directory location /ext4/ltp-2nHcAjcGKr/chd2Y4XkO/object not
equal to expected //ext4/ltp-2nHcAjcGKr/chd2Y4XkO/object
