tests/tst-kill: set flag global to 0 before waiting for 1
The global was already set to 1 by kill above second wait loop.
If test VM/program was "slow" enough, the signal handler got cleaned
before "oldact.sa_handler == SIG_DFL" check (debug build, nested VM,
slow enough report printout). The test tended to fail when VM run on
physical host.
Fixes #861
