prevented /etc/resolv.conf inotify detection from working

There were errors in configure script when /bin/sh was not bash
./configure: 15889: test: xfedora: unexpected operator
./configure: 19981: test: xyes: unexpected operator
./configure: 23103: test: x1: unexpected operator

The equality operator "==" works in bash but it's not a standard.
The man page test(1) also does not mention it.
There is only short version "="

       STRING1 = STRING2
              the strings are equal

Add another dollar sign to have variable name substituted by m4 in
"cwrap.m4" further substituted with its value by shell in "configure".

Before, this:

    [ test x$2 = xyes]

would produce this in "configure" for uid_wrapper test:

     test xHAVE_UID_WRAPPER = xyes

which is always false.

Now the changed code:

    [ test x$$2 = xyes]

Would produce this in "configure" instead:

    test x$HAVE_UID_WRAPPER = xyes

which will properly process the test result.

This fixes uid_wrapper and nss_wrapper detection, which were considered
missing otherwise, resulting in cwrap tests not running.

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.

Add AM_PYTHON2_MODULE - an autoconf macro checking for presence of
Python 2 modules. This is for use with the upcoming integration tests
configuration, but can be used by other code as well.
