ping: main.c: Consistent use of white space/tabs

If a user has tabs set at a value other than 8, the output of the usage
may not be consistently aligned.

    % tabs -2

Before:
    % ping
    usage:
      ping [-4AaDdfHnoQqRrv] [-C pcp] [-c count] [-G sweepmaxsize]
          [-g sweepminsize] [-h sweepincrsize] [-i wait] [-l preload]
          [-M mask | time] [-m ttl] [-P policy] [-p pattern] [-S src_addr]
          [-s packetsize] [-t timeout] [-W waittime] [-z tos] IPv4-host
      ping [-4AaDdfHLnoQqRrv] [-C pcp] [-c count] [-I iface] [-i wait]
          [-l preload] [-M mask | time] [-m ttl] [-P policy] [-p pattern]
          [-S src_addr] [-s packetsize] [-T ttl] [-t timeout] [-W waittime]
                [-z tos] IPv4-mcast-group
      ping [-6AaDdfHnNoOquvyY] [-b bufsiz] [-c count] [-e gateway]
                [-I interface] [-i wait] [-k addrtype] [-l preload] [-m hoplimit]
                [-p pattern] [-P policy] [-S sourceaddr] [-s packetsize] [-t timeout]
          [-W waittime] [-z tclass] [IPv6-hops ...] IPv6-host

After:
    % ping
    usage:
      ping [-4AaDdfHnoQqRrv] [-C pcp] [-c count] [-G sweepmaxsize]
          [-g sweepminsize] [-h sweepincrsize] [-i wait] [-l preload]
          [-M mask | time] [-m ttl] [-P policy] [-p pattern] [-S src_addr]
          [-s packetsize] [-t timeout] [-W waittime] [-z tos] IPv4-host
      ping [-4AaDdfHLnoQqRrv] [-C pcp] [-c count] [-I iface] [-i wait]
          [-l preload] [-M mask | time] [-m ttl] [-P policy] [-p pattern]
          [-S src_addr] [-s packetsize] [-T ttl] [-t timeout] [-W waittime]
          [-z tos] IPv4-mcast-group
      ping [-6AaDdfHnNoOquvyY] [-b bufsiz] [-c count] [-e gateway]
          [-I interface] [-i wait] [-k addrtype] [-l preload] [-m hoplimit]
          [-p pattern] [-P policy] [-S sourceaddr] [-s packetsize] [-t timeout]
