Fix log output for Synaptics touch updates

The log output for the Synaptics touch FW updater is pretty clunky when
it can't find a binary.  Essentially the log outputs were clobbering
eachother.  This CL makes the script die faster to prevent extra logging
that's confusing.

Shoot, turns out this caused a regression in the touch_updater scripts for Synaptics due to a bash vs sh mistake.  One of the conditionals was evaluating to False accidentally, even when it should've been true.

Reverting now.  I'll submit a fixed patch later once everything's back into working order again.

Patch is reverted in ToT

Make Synaptics update fail sooner if FW isnt found

This is a second attempt at fixing the logs output on Synaptics touch FW
updater.  When a FW wasn't found on disk there was a lot of extra logs
output that makes it hard to read.  This CL makes the script fail out
sooner, if no FW is found which makes the logs easier to read.
This is essentially the same approach as the first fix (that got
reverted) except that the if conditional has been reformatted to work
with sh better.  Previously a bash vs sh issue cause the conditional to
be evaluated incorrectly.

BUG= chromium:613719 
TEST=This was the fix I found when debugging when the last version
failed.  The conditional seems to work correctly now

Okay, it should actually work this time (knock on wood)
