dh: Skips running commands that it can tell do nothing.

This is determined by the presence of special PROMISE directives within
commands that provide a high-level description of the command.

Note that when dh is passed additional debhelper options, it cannot tell if
these change the behavior of commands, and so it stops skipping any
commands.
