travis-ci: check that all build artifacts are .gitignore-d

Every once in a while our explicit .gitignore files get out of sync when our build process learns to create new artifacts, like test helper executables, but the .gitignore files are not updated accordingly. Use Travis CI to help catch such issues earlier: check that there are no untracked files at the end of any build jobs building Git (i.e. the 64 bit Clang and GCC Linux and OSX build jobs, plus the GETTEXT_POISON and 32 bit Linux build jobs) or its documentation, and fail the build job if there are any present.
