Skip slow tests when kmemleak is enabled

When running the ZFS Test Suite with a kmemleak enabled kernel
the following test cases run far slower than usual and may hit
their timeout threshold.  Skip the following test cases.

Test: cli_root/zfs_get/zfs_get_009_pos (run as root) [55:43]
Test: cli_root/zpool_clear/zpool_clear_001_pos (run as root) [11:32]
Test: cli_root/zpool_create/zpool_create_024_pos (run as root) [11:01]
Test: features/async_destroy/async_destroy_001_pos (run as root) [41:15]
Test: inheritance/inherit_001_pos (run as root) [09:08]
