column: --separator segfaults

The --separator and --columns long options in util-linux-2.21.2 and in
a git clone from 5 minutes ago, don't work:

$ echo foobar | column -s x
foobar

$ echo foobar | column -c 10
foobar

$ echo foobar | column --separator=x
column: option '--separator' doesn't allow an argument

$ echo foobar | column --separator x
Segmentation fault

$ echo foobar | column --columns 10
column: bad columns width value: '(null)': Invalid argument

$ echo foobar | column --columns=10
column: option '--columns' doesn't allow an argument

Looks like a simple case of missing has_arg flag in the "struct
option" initialization for these two options. The patch just adds the
flag. I haven't done thorough testing of the patched code, but it
seems to work OK and it no longer segfaults or tries to dereference a
null pointer.
