[PATCH olang v3 0/2] add integration test

[Carlos Maniero <carlos@maniero.me>]

This patch is divided by two commits, the first is a copy of the
customer version of munit cloned from pipalang. The second is a
integration test setup that ensures the 0c binary is there and is
executable.

This patchset apply the changes suggested by johnny@johnnyrichard.com on
20240215162146.847336-1-carlos@maniero.me.

v2:
  - uses perror and exit instead of assert
  - replace make with $(MAKE) on Makefile
  - create a check target on make to run all tests
  - make linter and linter-fix to lint all files
    - Although I still delegating the linter stuff to integration's
      Makefile the reason is because I have to remove munit files from
      the list to be linted since these files takes a long time to be
      processed and I don't wanna leak this detail to the global
      Makefile.

v3:
  - I fail linter.

Carlos Maniero (2):
  tests: add munit testing framework file
  tests: add integration test setup
