Bug 1403478 - part1 : check v.seekable before and after calling ms.endOfStream(). r=jwwang,jya 

This patch does two things,

(1) check v.seekable after calling ms.endOfStream()
As test name suggests, we check seekable after calling endOfStream()

(2) check the time range of v.seekable
The seekable represents the ranges of the media resource [1], so it would be changed after calling ms.endOfStream().

Before calling the endOfStream(), seekable should be [0, ms.duration)
After calling the endOfStream(), seekable should be [0, ms.buffer.end(0))
