[Buildroot] [PATCH 1/1] package/openssh: fix musl compile issue

[Fiona Klute via buildroot]

From: "Fiona Klute (WIWA)" <fiona.klute@gmx.de>

Building package/openssh 9.9p1 with musl failed during linking because
construct_utmp() was referenced due to "use construct_utmp to
construct btmp records" [1], but not built as utmp is disabled in the
Buildroot package. The fix comes from upstream and ensures the
construct_utmp function actually gets built when USE_BTMP is set [2].

It would have been nice to include more explicitly since when this
issue started occurring. I assume it's since the bump of OpenSSH to
9.9p1, but this should ideally been made explicit. Could you keep this
in mind for your next fixes?

I've also added a reference to the autobuilder failure being fixed, and
applied. Thanks!
