[libc] Make hermetic test syscall deps linux-only (#210715)

They are only used on linux, so this matches that.

They are also only used in full build mode, but hermetic tests only work
in full build mode, so we don't need to check that here. The darwin
check is a noop as (AAIU) we don't support full_build on darwin, but
I've kept it for symmetry.

Git commit 375231d8ea9b4f5a3a71f4afb3d76ba6e1dcefc5 by GitHub (on behalf of Pavel Labath) on 21/07/2026 at 05:19..
[libc] Add struct group_req, struct group_source_req, and related socket options (#210029)

Add definitions for struct group_req and struct group_source_req in
llvm-libc-types and wire them into <netinet/in.h>.

Also define the multicast socket options using these structs:
- MCAST_JOIN_GROUP
- MCAST_LEAVE_GROUP
- MCAST_BLOCK_SOURCE
- MCAST_UNBLOCK_SOURCE
- MCAST_JOIN_SOURCE_GROUP
- MCAST_LEAVE_SOURCE_GROUP

Add layout assertions for struct group_req and struct group_source_req
to the netinet/in.h unit test.

Assisted by Gemini.
