Add atomic operations to package.conf.in

This patch resulted from the discussion in D2431 and should be merged
first.

@erikd and @trommler reported errors like

```

on PowerPC. @simonmar suggests to add the specific exports to
`rts/package.conf.in`. This patch does exactly that, including all
other atomic ops as they probably (maybe someone can verify?) suffer
from the same problem on PPC.

Test Plan: Please make sure to build on PPC.
