New tagged release for crates.io using cfg-if = "1"

[Dragonrun1]

So the master has been switch to using cfg-if v1 but the getrandom v0.2.0 on crates.io is still on the older version. Now that rand v0.8.0 has been released using cfg-if v1 it would be nice to have a published version of getrandom that has done the same.

This repository is set in a such way that merging PRs (including release PRs) requires an approval from another maintainer (effectively this repository has just two maintainers myself and @josephlr), so unfortunately I can't do a proper release by myself (well, I have publishing rights, but I don't want to do a release without changing code in the repository).

@josephlr
Would you like to cut a release before merging the pending PRs? I would prefer to merge the PRs first and release v0.2.1 with all accumulated changes.

@newpavlov I'll should be able to get to these tomorrow, after I merge, I'll cut 0.2.1

getrandom v0.2.1 has been published https://crates.io/crates/getrandom/0.2.1

Now that this and v0.1.16 have been released, this issue can be closed.
