termios: consolidate values for VDISCARD in INIT_C_CC
On old systems it used to be ^O. Linux had never actually used the value, but INIT_C_CC (on i386) did initialize it to ^O; unfortunately, it had a typo in the comment claiming that to be ^U. Most of the architectures copied the (correct) definition along with mistaken comment. alpha, powerpc and sparc tried to make the definition match comment. However, util-linux still resets it to ^O on any architecture, ^O is the historical value, kernel ignores it anyway and finally, Linus said "Just change everybody to do the same, nobody cares about VDISCARD".
