Rusty Russell 7401b26824 cleanup: remove unneeded includes in C files.
Before:
 Ten builds, laptop -j5, no ccache:

```
real	0m36.686000-38.956000(38.608+/-0.65)s
user	2m32.864000-42.253000(40.7545+/-2.7)s
sys	0m16.618000-18.316000(17.8531+/-0.48)s
```

 Ten builds, laptop -j5, ccache (warm):

```
real	0m8.212000-8.577000(8.39989+/-0.13)s
user	0m12.731000-13.212000(12.9751+/-0.17)s
sys	0m3.697000-3.902000(3.83722+/-0.064)s
```

After:
 Ten builds, laptop -j5, no ccache: 8% faster
