Add integration tests

Add "intgcheck" make target. Update CI to use it.

The "intgcheck" target configures and builds sssd in a sub-directory,
installs it into a prefix in another sub-directory, and then makes the
"intgcheck-installed" target from within src/tests/intg in that separate
build.

The "intgcheck-installed" target in src/tests/intg runs py.test for all
tests it can find in that directory, under fakeroot and
nss_wrapper/uid_wrapper environments emulating running under root.
It also adds the value of INTGCHECK_PYTEST_ARGS environment/make
variable to the py.test command line. You can use it to pass additional
py.test options, such as specifying a subset of tests to run. See
"py.test --help" output.

There are only two test suites in src/tests/intg at the moment:
ent_test.py and ldap_test.py.

The ent_test.py runs tests on ent.py - a module of assertion functions
for checking entries in NSS database (passwd and group), for use in
actual tests. The ent_test.py suite can be used as ent.py usage
reference.

The ldap_test.py suite sets up and starts a slapd instance, adds a few
user and group entries, configures and starts sssd and verifies that
those users and groups are retrieved correctly using various NSS
functions. The tests are very basic at the moment.
