ltp: fix hanging issue for gdb01 case
If gdb01 testcase runs as background process, gdb can receive SIGTTOU and then the case gets stuck. Replace stdin with /dev/null to fix this issue. The patch is backported from upstream. Signed-off-by: Yi Zhao <yi.zhao@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com>
