Pekka Enberg fad6712673 dbuild: Improve error message if Docker is not installed ...

If you run "dbuild" on a freshly installed machine, the error message is
not the most helpful one. Fix it up.

Before:

  $ ./tools/toolchain/dbuild
  ./tools/toolchain/dbuild: line 113: docker: command not found
  ./tools/toolchain/dbuild: line 156: docker: command not found

After:

  $ ./tools/toolchain/dbuild
  dbuild: Please install Docker on this machine to run dbuild.

  Run `./tools/toolchain/dbuild --help' to print the full help message.
