SELinux: call cap_file_mmap in selinux_file_mmap
Currently SELinux does not check CAP_SYS_RAWIO in the file_mmap hook. This means there is no DAC check on the ability to mmap low addresses in the memory space. This function adds the DAC check for CAP_SYS_RAWIO while maintaining the selinux check on mmap_zero. This means that processes which need to mmap low memory will need CAP_SYS_RAWIO and mmap_zero but will NOT need the SELinux sys_rawio capability.
