Description:
This is a request from webscale

An obsolete hard-coded limit in mtr prevented testing using aio with --mem.

Confirmed this is completely obsolete in all our kernels, then removed it.

Note: This bug was fixed in the linux-2.6.27 release:

https://github.com/webscalesql/webscalesql-5.6/commit/267ba59ea08f248b61bc83d29361e6943293...

How to repeat:
Examine code

 # On some old linux kernels, aio on tmpfs is not supported
  # Remove this if/when Bug #58421 fixes this in the server
  if ($^O eq "linux" && $opt_mem) {
    mtr_add_arg($args, "--loose-skip-innodb-use-native-aio");
  }

Suggested fix:
Removed mentioned lines
