[PATCH 1/4] python/sepolgen: close /etc/selinux/sepolgen.conf after parsing it

[Nicolas Iooss <nicolas.iooss@m4x.org>]

sepolgen testsuite reports the following warning on a system with
/etc/selinux/sepolgen.conf:

    .../src/./sepolgen/defaults.py:35: ResourceWarning: unclosed file
    <_io.TextIOWrapper name='/etc/selinux/sepolgen.conf' mode='r'
    encoding='UTF-8'>

Fix this by properly closing the file in PathChooser.__init__().
