Fix ionice.
ioprio_set takes a "prio" argument that combines class and level. Although
bionic (via the uapi headers) includes the appropriate constants and even
a convenience macro, glibc doesn't, so just hard-code the encoding.
Also fix the sense of a conditional so we actually execute the provided
command.
