evemu-record.c: Fix evemu-describe writing to output file
We had incremented the argv pointer once too often here. What was read
is some buffer outside of our scope, not the next argument after the
device. Right before, "prefix" is already set up to point to the user's
output file path. Let's use it.
I guess people work around and always use redirection of stdout in order
to get a file instead. This makes writing directly work.
