[pxe] Add a dummy PXENV+ entry point at UNDI_CS:0000
Wyse Streaming Manager server (WLDRM13.BIN) assumes that the PXENV+ entry point is at UNDI_CS:0000; apparently, somebody at Wyse has difficulty distinguishing between the words "may" and "must"... Add a dummy entry point at UNDI_CS:0000, which just jumps to the correct entry point.
