Francisco Molina 416c048737 tests: add test_utils_interactive_sync when possible 
- Define test_utils_interactive_sync as DEFAULT_MODULE in Makefile.tests_common
- For tests disabling autoinit, add test_utils_interactive_sync to main
- Add DISABLE_MODULE += test_utils_interactive_sync for tests requiring
  sudo,  `tests/shell`, `tests/minimal` and `tests/stdin`
- Add shell_commands to tests/periph_wdt and tests/struct_tm_utility to
  pull `r` and `s` commands
- Remove includes and usage in `tests/main.c` for tests that where
  already using test_utils_interactive_sync

Expected result

This application increases a non-even floating point number in steps of 0.1 starting from from 1234567.0 / 1024.0 ~= 1205.631835938. For each step it checks if the sum minus its 'floored' values is less than 1.0 (which it should always be by definition of floor).

Background

This test was introduced due to an error for floating point handling in an older newlib version.

The idea for this test is taken from: http://sourceware.org/ml/newlib/2010/msg00149.html
