Jeff Dike 00a905e614 uml: don't kill pid 0 ...

A bit of defensive programming - during development, it ocassionally
happens that a call to init_new_context is missed, resulting in
context holding a host pid of zero.  When that address space is torn
down, destroy_context does a kill(0), which instantly kills the whole
UML without any errors whatsoever.

This patch add a check for pids less than 2, to also catch 1 and
negative pids.
