mysql_upgrade portability fixes

client/mysql_upgrade.c:
  Add defines for WEXITSTATUS
  Pass arguments on command line instead of --defaults-file=<temp file>
mysql-test/r/mysql_upgrade.result:
  When testing that mysql_upgrade detect if mysqlcheck fails, use an option that
  is used on all platforms.
mysql-test/t/mysql_upgrade.test:
  When testing that mysql_upgrade detect if mysqlcheck fails, use an option that
  is used on all platforms.
scripts/comp_sql.c:
  Some compilers have a max string length, insert a newline at
  every 512th char in long strings
