[LTP] [PATCH 2/4] openposix: Makefile: Add the standard "maintainer-clean" target

[rbm@suse.com]

From: Ricardo B. Marlière <rbm@suse.com>

The include/mk/automake.mk file define the standard "maintainer-clean" and
"ac-maintainer-clean" targets and therein it calls the same targets under
each AUTOCONFED_SUBDIRS, but in the case of the openposix test suite, they
don't exist. Add them and also remove some dangling files in ac-clean.

This fixes the following error when calling `make maintainer-clean` from
the project's top level directory:

make[1]: Entering directory './testcases/open_posix_testsuite'
make[1]: *** No rule to make target 'ac-maintainer-clean'.  Stop.
make[1]: Leaving directory './testcases/open_posix_testsuite'
make: *** [./include/mk/automake.mk:68: ac-maintainer-clean] Error 2
