[coreboot] lar -l total patch

[Myles Watson]

This patch makes lar -l print a total of the bytes used in an archive.
 I did it because I wanted to know the differences between preparsing
elf files and compressing the pieces.  Here is the output from a few
of them:

Coreboot v3 with filo.elf added using lar -a

  normal/option_table (932 bytes @0x50);loadaddress 0x0 entry 0x0
  normal/stage2/segment0 (191792 bytes, lzma compressed to 110 bytes
@0x450);loadaddress 0x0xa1c0 entry 0x0x2000
  normal/stage2/segment1 (28084 bytes, lzma compressed to 14976 bytes
@0x510);loadaddress 0x0x2000 entry 0x0x2000
  normal/stage2/segment2 (4540 bytes, lzma compressed to 316 bytes

@0xeac0);loadaddress 0x0x13cd60 entry 0x0x10e51c
  bootblock (20480 bytes @0xfb000)
Total size = 80381 bytes (0x139fd)

I'm not sure I counted everything right, but I think this is a feature
that lar ought to have (space left in the archive is just as good for
me.)
