Fix a ps.test failure in 5.0-runtime tree.

mysql-test/r/ps.result:
  Update result files.
mysql-test/t/ps.test:
  Disable result ouptut of SHOW CREATE TABLE: DATA DIRECTORY option
  may be present or absent from the output depending on the build
  otpions and the operating system, so the output is not consistent
  across supported platforms.
sql/mysqld.cc:
  Remove a tricky #ifdef dependency of --use-symbolic-links on PURIFY
  added in 2002: DEBUG options should not influence server functionality.
  This backfired by producing different output of SHOW CREATE TABLE
  depending on the build options (see also Bug#25677 "With 
  --skip-symbolic-links option on, DATA DIRECTORY clause
  is silently ignored".
