Bug#893600: clang-tidy-4.0: Should depend on clang-tools-4.0

[Alberto Luaces]

Package: clang-tidy-4.0
Version: 1:4.0.1-10
Severity: normal

Dear Maintainer,

if clang-tools-4.0 is not installed, running `run-clang-tidy` and the
option `-fix` results in an unhandled python exception about a missing
file.  Upon closer examination with the debugger, it is apparent that
the missing script/file is provided by the other package.

Installing it makes `-fix` work again.
