[PATCH] ia64: fix unwcheck.py for python3

[Meelis Roos <mroos@linux.ee>]

In Gentoo, Python3 is the default Python and our unwcheck.py breaks with 
Python 3. Fix it:

 * Close % substitutions of strings in parens to avoid syntax errors
 * make long code portable as per 
   http://python3porting.com/differences.html#long - define long for 
   Python3 and use long(0) instead of 0L for Python2.

Tested to still work with Python2 too (at least it omits no errors).
