perf record: Fix eternal wait for stillborn child
When execvp fails to find the specified command on the path we won't get
SIGCHLD, so send a SIGUSR1 and exit right away.
Current situation would require a SIGINT performed by the user and would
produce meaningless summary.
Now:
[acme@emilia linux]$ ./foo
-bash: ./foo: No such file or directory
[acme@emilia linux]$ perf record ./foo
./foo: No such file or directory
[acme@emilia linux]$
