Andries Kruithof 226c99b455 tests: bluetooth: add prefix to exposed API 
In ull_llcp* some functions used in unittesting did not have
the llcp_ prefix
Although this is not a big issue since they are only used when
testing the module this commit adds the prefix so that we
have a more consistent naming
