[LTP] Bugfix for sendmsg01.c

[Gernot P. <gp...@su...>]

Hi,

in this file there is a line in cleanup() "kill(pid, SIGKILL);" where pid is the
return code of a function, which starts a child process and returns the pid.
Unfortunately in case of an error this function returns -1, so
if ltp is run as root (quite probable) all processes except init are killed.
This patch should prevent this case:
