build: Prefix missed generated syscall includes

PR #63973 namespaced generated headers with zephyr/, including generated
syscall headers.

Since then, some new generated syscall header includes have been added
without the zephyr/ prefix, breaking builds when
CONFIG_LEGACY_GENERATED_INCLUDE_PATH is disabled.

This commit adds the zephyr/ prefix to includes for generated syscall
headers where it has been missed.
