[PATCH] usb: fix u2f build

[Gerd Hoffmann]

Just use qemu_open_old() for a quick fix, switch
to better error handling left for another day.

Fixes: 448058aa99aa ("util: rename qemu_open() to qemu_open_old()")

BTW, this breakage shows that we're missing CI coverage for this
feature. the pre-requisite library needs to be added to any of the
dockerfiles where it is available and ensure its covered by at least
one of the gitlab CI jobs that exists.
