This will make it easier to share with the downgrade tool. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
When installed, the name is `lightning-hsmtool`. We actually copy `tools/hsmtool` to `tools/lightning-hsmtool` but that's a silly step which we should get rid of. So: 1. Make sure our documentation always refers to it as lightning-hsmtool. 2. Make sure our tests invoke it as `lightning-hsmtool`. 3. Rename the C file.

And leave $(TOOLS) as user-visible tools. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Fairly easy, for this release. The real problem was writing the tests!
