uml: tidy helper code
Style fixes to arch/um/os/helper.c and tidying up the breakpoint fix a
bit.
helper.c gets all the usual style fixes -
updated copyright
all printks get severities
Also -
errval changes to err in helper_child
fixed an obsolete comment
run_helper was killing a child process which is guaranteed to
be dead or dying anyway
Removed the nohang and pname arguments from helper_wait and fixed the
declaration and callers. nohang was used only in the slirp driver and
I don't think it was needed. I think pname was a bit of overkill in
putting out an error message when something goes wrong.
