Fixed BUG#5258: Stored procedure modified date is 0000-00-00.

  Althought techically not a but (as it's functioning as designed),
  it was decided that the design should be changed. Some users have
  a problem with dates being '0000-00-00' and the SQL standard specifies
  that the modification date should be the same as the creation date
  at creation.


mysql-test/r/sp.result:
  New test case for BUG#5258.
mysql-test/t/sp.test:
  New test case for BUG#5258.
sql/sp.cc:
  Set the modification time at creation too.
