[PATCH] commands: digest: show area info only if necessary

[Antony Pavlov]

Area info "0x00000000 ... 0xffffffffffffffff" in digest
commands output is something strange and misleading, e.g.

  barebox at barebox sandbox:/ md5sum logo/barebox-logo-240.png
  d3226a0eba3fd49af6bd190b077a3466  logo/barebox-logo-240.png 0x00000000 ... 0xffffffffffffffff

Also skipping area info in the barebox digets commands
output for every file makes it more similar to traditional
*nix digest commands output.
