util/fipstools/acvp/acvptool: buffer signal channel to avoid losing signal

The docs at os/signal.Notify warn about this signal delivery loss bug at
https://golang.org/pkg/os/signal/#Notify, which says:

    Package signal will not block sending to c: the caller must ensure
    that c has sufficient buffer space to keep up with the expected signal
    rate. For a channel used for notification of just one signal value,
    a buffer of size 1 is sufficient.

Discovered by one of Orijtech, Inc's internal static
analyzers that will eventually be donated to the Go project, and will
then be included when one runs:
    go test
