build: fix several issues with building tests

- MAINTAINERCLEANFILES should not rely on conditionals
  that could or could not clean files.

- EXTRA_DIST should not rely on conditonals that could
  or could not add files to the final tarball.
  sources should always ship.

- CLEANFILES should not rely on conditionals as
  ./configure can be done in between builds leaving
  stray files around.

- (cosmetic) move distclean-local: target with clean-local.

- drop old ipc_sock.test, start.test and resources.test
  shell files.

- fix make distcheck -j:
  - stop shipping or not shipping libstat_wrapper.so.
    libtool will only generate the .so when installing
    a shared library (--enable-install-tests).
  - make libstat_wrapper a module in a similar fashion
    of _failure_injection.
  - build ipc_sock.test in a similar fashion as ipc.test
    and link as module _libstat_wrapper.la.
    this solves multiple issues of having the binary
    in the final test builddir, no need to detect if
    libstat_wrapper.so is installed or not and workaround
    libtool different linking methods for inst vs noinst
    libraries.

- fix ipc.test linking with GLIB that should not be
  dependent on HAVE_FAILURE_INJECTION.

Run tests in parallel with dependancies
Make sure the two IPC tests use different socket names
Shortedn some names so they fit with the new ipc-names
remove ipc-test-name-sock
Fix resources.test now that ipc_sock is being run properly
