[PATCH] Linux: Use kill_lwp/tkill instead of kill when killing a, process

[Pedro Alves <palves@redhat.com>]

Another thing I noticed by inspection while fixing the
recent gdbserver kill crash.

Anyone know a reason we use plain "kill" here, instead
of tkill like everywhere else?

Passes testing on x86_64 Fedora 20 for me, at least...

Since we use tkill everywhere, using kill to try to kill each lwp
individually looks suspiciously odd.  We should really be using tgkill
everywhere, but at least while we don't get there this makes us
consistent.
