The problem was in dummy grep on AIX and HPUX.
The fix is to use more portable patterns.
The patch is only for test suite
(i.e. does not touch server codebase).
mysql-test/r/im_instance_conf.result:
Updated result file.
mysql-test/t/disabled.def:
Fix typo.
mysql-test/t/im_instance_conf.imtest:
Make grep-pattern aix/hpux-compatible.
mysql-test/t/im_options.imtest:
Make grep-pattern aix/hpux-compatible.
mysql-test/t/im_options-im.opt:
Speedup IM-tests.
