python-smartpm: truncate the filename to meet NAME_MAX

There is a "File name too long" error when len(TMPDIR) = 410, this is
because the function getLocalPath() converts the filepath into the
filename, so there would be the error when len(filename)
> NAME_MAX, truncate the filename to meet NAME_MAX will fix the problem.
