[meta-selinux][PATCH] libselinux-python: Fix one invalid link

[Changqing Li]

From: Changqing Li <changqing.li@windriver.com>

when host arch and target arch are different, the extension
suffix of host is different with target one, so there will
be a invalid link.  Fix by update the way to create the link.

+Subject: [PATCH] Do not use PYCEXT, and rely on the installed file name
+
+PYCEXT is computed by asking the Python intrepreter what is the
+file extension used for native Python modules.
+
+Unfortunately, when cross-compiling, the host Python doesn't give the
+proper result: it gives the result matching the build machine, and not
+the target machine. Due to this, the symlink has an incorrect name,
+and doesn't point to the .so file that was actually built/installed.
+
+To address this and keep things simple, this patch just changes the ln
+invocation to rely on the name of the _selinux*.so Python module that
+was installed.
