cmd/link/internal/ld: set MachO platform to PLATFORM_IOS on iOS
CL 205340 changed the linker to skip certain flags when linking
for iOS. However, for host linking on iOS (such as on the Corellium
darwin/arm64 builders) the MachO platform defaults to PLATFORM_MACOS,
and the flags are not skipped.
Avoids warnings such as
ld: warning: -no_pie ignored for arm64
Updates #32963
