Make Tomato's OS_VERSION shorter to stop SendSSDPNotify log messages

As discussed in this thread:
http://www.linksysinfo.org/index.php?threads/tomato-shibbys-releases.33858/page-53#post-262636

It appears that the Tomato OS_VERSION has gotten long enough, that it's causing SSDP_PACKET_MAX_LEN being larger than 512 by a few characters.

This change reduces unnecessary "verbiage" at the end of the Tomato OS_VERSION string.

In short, what was previously (as example):
     Tomato 1.28.0000 MIPSR2-130 K26AC USB AIO-64K
 will become
     Tomato MIPSR2-130 K26AC
