A few patches slightly improving the output generated by
decode_stacktrace.sh.


This patch (of 3):

Lines having a symbol to decode might not always have info after this
symbol.  It means ${info_str} might not be set, but it will always be
printed after a space, causing trailing whitespaces.

That's a detail, but when the output is opened with an editor marking
these trailing whitespaces, that's a bit disturbing.  It is easy to remove
them by printing this variable with a space only if it is set.

While at it, do the same with ${module} and print everything in one line.
