scsi: MAINTAINERS: Add header files to SCSI SUBSYSTEM

This is part of an effort to assign a section in MAINTAINERS to header
files that relate to Networking [1]. In this case the files with "net" in
their name.

[1] https://lore.kernel.org/netdev/20240816-net-mnt-v1-0-ef946b47ced4@kernel.org/

As part of that effort these files came up:

 * include/uapi/scsi/scsi_netlink_fc.h
 * include/uapi/scsi/scsi_netlink.h

Unlike all the other matching files, these one seem to relate more closely
to SCSI than Networking, so I have added them to the SCSI SUBSYSTEM
section.

In order to simplify things, and for consistency, I have added the entire
include/uapi/scsi rather than the individual files.
