[PATCH][LTTV] take account of the byte order when reading event ids

Hi all,

I tried to view a trace, which has been captured on a powerpc target, on
my x86 based host and ran into some trouble (lttv was parsing wrong
event IDs). I'm using lttv-0.10.0-pre4-28112007. The trace was captured
with 2.6.24-rc3-git1-lttng-0.10-pre3 on a MPC8548CDS.

Attached patch fixes things for me.

Cheers,
	Jan
