Fix this warning:
ipl.c: In function 'iplmain':
ipl.c:644:33: warning: 'sprintf' may write a terminating nul past the end of the destination [-Wformat-overflow=]
     sprintf(kern_fullname, "%d%s", kern_part, kern_name);
                                 ^
ipl.c:644:5: note: 'sprintf' output between 2 and 139 bytes into a destination of size 128
