Enable clang-tidy job on Travis

This runs predefined clang-tidy checks on the QBS sources, excluding
examples and tests

Most checks are displayed as warings, however, some checks are treated
as errors to avoid adding regressions in the new code

clang-analyzer-* checks are not enabled due to performance reasons
(otherwise, Travis job hits 50 min)
