[PATCH master] scripts: fix build failure with glibc 2.43

[Ahmad Fatoum]

From: Hemanth Kumar M D <Hemanth.KumarMD@windriver.com>

glibc 2.43 introduces linux/openat2.h through the fcntl include chain
(bits/fcntl-linux.h -> linux/openat2.h). This header expects the
__u64 type to be defined before inclusion.

In barebox scripts/include/linux/types.h the header <fcntl.h> was
included before the __u64 typedef, causing build failures such as:

  linux/openat2.h:20:9: error: unknown type name '__u64'

Move the inclusion of <fcntl.h> after the typedef definitions so that
__u64 and related types are defined before linux/openat2.h is parsed.
