test: initialize a variable to make scan-build happy

Assuming safe_atoi works as expected, `fuzz` cannot be
uninitialized by the time we get here. But let's init it anyway to make
scan-build happy.

[202/249] Compiling C object libinput-test-suite.p/test_test-touch.c.o
../../../test/test-touch.c:964:2: warning: Assigned value is garbage or undefined [core.uninitialized.Assign]
  964 |         litest_assert_int_eq(fuzz, 10); /* device-specific */
      |         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Note that this error message is the result of a follow-up commit,
this commit is shuffled before so we have bisectable build.
