tests: remove cflag -w and fix warnings

The flag hides errors. But we want unit tests to be correct in order
to reveal errors in the main code.

The patch removes tests_unittests_unittests_CFLAGS which makes autotools
use AM_CFLAGS instead. Therefore, unit tests are built with flags
derived from configure.ac.
