uvol: replace with re-write in ucode

Replace previous Shell draft-quality implementation of uvol with a
rewrite in ucode[1].
While the new code is slightly larger, it performs much better (as
we no longer fork() for parsing strings like in Shell with grep, sed
and friends).

Before:
  time uvol list -j
  [ ... ]
  real	0m 0.82s
  user	0m 0.13s
  sys	0m 0.10s

After:
  time uvol list -j
  [ ... ]
  real	0m 0.47s
  user	0m 0.05s
  sys	0m 0.05s
