    Fix uses of deprecated SELinux security_context_t
    
    SELinux has used 'char *' in place of its typedef
    'security_context_t' since 2014 (v2.3) because the latter was
    inconvenient to use when paired with the 'const' qualifier.  The
    typedef has been kept around for compatibility with legacy callers,
    but it is deprecated in SELinux v3.1.  See the following URL for the
    relevant announcement:
    
https://lore.kernel.org/selinux/20200710162034.GC1768200@localhost.localdomain/
    
    * src/fileio.c (Fcopy_file, Ffile_selinux_context)
    (Fset_file_selinux_context) [HAVE_LIBSELINUX]: Replace deprecated
    'security_context_t' typedef with the equivalent 'char *'.
