corrected a variable type for python "b", i.e., from uint16 to uint8.

this fixes the recent build failure on sparc:
http://bind10.isc.org/~tester/builder//BIND10/20100929022000-Solaris10-sparc/logs/unittests.out

directly committing to trunk, as I believe it's quite trivial and it's a
sort of urgent care fix.
