SELinux: Auto-generate security_is_socket_class
The security_is_socket_class() is auto-generated by genheaders based on classmap.h to reduce maintenance effort when a new class is defined in SELinux kernel. The name for any socket class should be suffixed by "socket" and doesn't contain more than one substr of "socket".
