[Buildroot] [git commit branch/next] boot/uboot: add host-python-pylibfdt dependency if needed

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=9488ec2b58d94b1bd4954dc5348626e94b3e79ac
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/next

Until now, BR2_TARGET_UBOOT_NEEDS_PYLIBFDT was only bringing host-swig
as a dependency, because U-Boot was building its own pylibfdt, which
requires host-swig.

However, since commit
231d79c81e9a1f8c2ef14861374a40fcdc5e6b33 ("boot/uboot: set DTC path
when BR2_TARGET_UBOOT_NEEDS_DTC"), in which we tell U-Boot to use the
Buildroot built DTC, a consequence is that U-Boot no longer builds its
own pylibfdt: it expects the system to provided it. So now,
BR2_TARGET_UBOOT_NEEDS_PYLIBFDT really needs to bring
host-python-pylibfdt. The dependency on host-swig is no longer needed,
as what we need is host-python-pylibfdt, and it is an internal detail
of pylibfdt that it needs host-swig to build.

Fixes:
