Upgrade dlmalloc to version 0.2

In preparation of adding dynamic memory management support for SGXv2-enabled platforms, the dlmalloc crate has been refactored. More specifically, support has been added to implement platform specification outside of the dlmalloc crate. (see alexcrichton/dlmalloc-rs#15)

This PR upgrades dlmalloc to version 0.2 for the `wasm` and `sgx` targets.

As the dlmalloc changes have received a positive review, but have not been merged yet, this PR contains a commit to prevent tidy from aborting CI prematurely.

Other similar tests check for symlink creation permissions before doing anything, this PR performs the same check for `symlink_hard_link` as well.
