nss: fix parallel build

There is a hack for building subdirectories before the parent directory. There is a bug in this which causes the EXPORTS and PRIVATE_EXPORTS targets to be built twice leading to a race condition.

@AGnau any opinions?

I do not think we need this actually, for two reasons:

1. We no longer use this package as far as I can tell.

2. It seems the issue has been solved differently upstream and we do have this commit in:

   https://github.com/nss-dev/nss/commit/48f1ec429a32e7329a54a4b667cf50de822c3619

I suggest just closing.
