Auto merge of #3148 - KoviRobi:add-reentrant-getmntent_r, r=JohnTitor

Add reentrant glibc getmntent_r

- \[x] Edit corresponding file(s) under `libc-test/semver` when you add/remove item(s)
- \[x] `rustc ci/style.rs && ./style src`
- \[ ] `cd libc-test && cargo test` (This might fail on your env due to environment difference between your env and CI. Ignore failures if you are not sure.)
  <details>
    <summary>**Maybe**, see the cargo test output -- I am unsure about the failures</summary>
