[PATCH]add termination-signal in __fork_flags()'s output

[Zhaolei]

Hi -

This patch adds termination-signal in __fork_flags()'s output.

For example:
syscall.fork's argstr before patch:
  CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID
syscall.fork's argstr after patch:
  CLONE_CHILD_CLEARTID|CLONE_CHILD_SETTID|SIGCHLD

If no objection, I will commit it.
