[BUG][PATCH] SEGV in kill during args parsing

[Alexey Fomenko]

Hi all,

A bug has been found. Steps to reproduce:
kill -9 '$'
That's all. While parsing arguments, in a try to translate given symbols
to a PID number there is a case when recently created pointer *end for the
unparsed part of argline doesn't get assigned (after bb_strtol tests the very
first symbol and fails, bb_strtol will return ret_EEANGE without assigning
endp: maybe, it would be safier to patch libbb/bb_strtonum.c to prevent such
cases in other placec ?), and as a result termination of this pointer
(*end = '\0') gives a SIGSEGV. Suggested patch fixes this by skipping the
usage of *end when it can be broken and doing the termination of *arg
