cmd/apidiff: in -incompatible mode, don't show header

Currently if there's some breaking change we're OK with, we have to do
something like this:

```
apidiff -incompatible | \
    grep -v ThingImOkWith | \
    grep -v "Incompatible changes" | \
    (! read)
```

This CL changes the -incompatible flag to not show the header, meaning we
don't have to grep exclude it out. The experience ends up being a bit nicer.

Also, apart from the scripting niceties we get from this CL, the header is not
really required if I already specified that I want incompatible changes.

exp

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
