[LTP] [PATCH v4 1/2] libltp: add support to mount tmpfs for EROFS testing

I've fixed this part of the changelog since we use tmpfs instead of bind
mount.

> Example of tests that can benefit from this are:
>   access04, mkdirat02, mknodat02, acct01, fchown04, mknod07 etc.

> This also allows for these tests to successfully run on Android.

And this comment as well.
