top: just respond to the increased command name length

The command name for running tasks is displayed by top
in a variable length field, so the increase from 16 to
64 bytes was not a problem. However, there's one place
where top is sensitive to length - insp_view_choice().

So, this patch just bumps a buffer used to display it.
