sstate: Handle sstate filenames longer than 255 characters
Many filesystems can't cope with filenames longer that 255 characters. Add code to detect this and truncate non-essential elements of the filename to stay within the limit. [YOCTO #13268] Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
