[PATCH 1/3] kbuild: make rq-offsets-file an explicit preparation dependency

[Vincent Mailhol <mailhol@kernel.org>]

The generated rq-offsets.h header is included by linux/sched.h and must
exist before compiling ordinary objects. Currently that header is
prepared indirectly through the missing-syscalls target.

Make prepare depend directly on rq-offsets-file. Because rq-offsets-file
depends on offsets-file, that other dependency can be removed.

Keep the rq-offsets-file dependency in missing-syscalls so that the
check can still run independently.
