partial bibrecord -> legacy.bibrecord

I have only moved one of the 'utilities' because the other has some dependencies  (we can see it tomorrow) but I is too a command line tool.

BTW: 
```
make[5]: *** No rule to make target `webdeposit_api_blueprint.py', needed by `all-am'.  Stop.
make[4]: *** [all-recursive] Error 1
make[3]: *** [all-recursive] Error 1
make[2]: *** [all-recursive] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2
```
