tools: Fix shadowed declaration in err.h
The error variable breaks build on CentOS 6.7, due to collision with
global error symbol:
CC util/evlist.o
cc1: warnings being treated as errors
In file included from util/evlist.c:28:
tools/include/linux/err.h: In function ‘ERR_PTR’:
tools/include/linux/err.h:34: error: declaration of ‘error’ shadows a global declaration
util/util.h:135: error: shadowed declaration is here
Using 'error_' name instead to fix it.

[ Use 'error_' instead of 'err' to, visually, not diverge too much from include/linux/err.h ]
