Integrate `init_mrbtest.c` to `driver.c` in `mruby-test` mrbgem

- `mrbgemtest_init()` is needed if `DISABLE_GEMS` is enabled because core
  tests are run as part of `mruby-test` mrbgem (moreover, `DISABLE_GEMS` is
  disabled when `enable_test` is used in build config).
- For the same reason `mrb_open_core()` etc for core tests is unneeded.
