[PATCH] sparse-checkout: improve OS ls compatibility

[Ed Maste <emaste@FreeBSD.org>]

On FreeBSD, when executed by root ls enables the '-A' option:

  -A  Include directory entries whose names begin with a dot (`.')
      except for . and ...  Automatically set for the super-user unless
      -I is specified.

Pipe ls's output to grep -v .git to remove the undesired entry.  Also
pass the -1 option to ensure one entry per line.

There are several different ways this could be solved; this approach
felt cleanest to me, but there are at least two other reasonable
alternatives:

  * Add -a to the invocations and .git to the expected output

  * Add LSFLAGS and set it to -I on BSDs, to turn off the special dot
    behaviour

I'll submit a new patch if a different approach is preferred.
