perf tools: Remove the '--(null)' long_name for --list-opts
If the long_name of a 'struct option' is defined as NULL, --list-opts will incorrectly print '--(null)' in its output. As a result, '--(null)' will finally appear in the case of bash completion, e.g. 'perf record --'.
Example:
Before this patch:
$ perf record --list-opts
--event --filter --pid --tid --realtime --no-buffering --raw-samples --all-cpus --cpu --count --output --no-inherit --freq --mmap-pages --group --(null) --call-graph --verbose --quiet --stat --data --timestamp --period --no-samples --no-buildid-cache --no-buildid --cgroup --delay --uid --branch-any --branch-filter --weight --transaction --per-thread --intr-regs
After this patch:
$ perf record --list-opts
--event --filter --pid --tid --realtime --no-buffering --raw-samples --all-cpus --cpu --count --output --no-inherit --freq --mmap-pages --group --call-graph --verbose --quiet --stat --data --timestamp --period --no-samples --no-buildid-cache --no-buildid --cgroup --delay --uid --branch-any --branch-filter --weight --transaction --per-thread --intr-regs
