intel-gpu-tools: add igt_core init func calls to some tests

igt-core.h/c provides some macros and initialisation
functions to support the tests but some of the single
tests do not use these. Modifying these tests to use
the igt_simple_main macro and igt_simple_init function
is the first step towards a consistent command line
across all tests.
