ifup-eth: use 'bc' instead of 'expr' when computing $forward_delay

  Because the return value of 'convert2sec()' function can sometimes be
  decimal, the follow up 'expr' call can fail, since 'expr' does not
  support floating point calculations. This can sometimes lead to error:

  """
  expr: non-integer argument
  /etc/sysconfig/network-scripts/ifup-eth: line 91: [: 0: unary operator
  expected
  """

  To solve this bug, we switch to 'bc' utility, which supports floating
  point computations. We also have to change the comparison condition of
  $LINKDELAY and $forward_delay to use 'bc' as well.
