list_hardware.py: sort rglob(SOC_YML) HWMv2 results
This makes .config, autoconf.h, and configs.c deterministic again.
Directory listing is not deterministic, it must always be sorted.

Fixes commit 61bbfb5ba25f ("scripts: introduce list_hardware.py for
listing of architectures and SoCs") in collab-hwm branch which was
squashed in mega HWMv2 commit 8dc3f856229c ("hwmv2: Introduce Hardware
model version 2 and convert devices")
SOF CI builds with both Windows and Linux and compares the outputs. This
catches practically 100% of build reproducibility issues and caught this
one too:
https://github.com/thesofproject/sof/actions/runs/8241692987/job/22539664560
HWMv2 was a "big bang" integration on both the Zephyr and SOF sides. So
this `rglob()` was a needle in a haystack but with hindsight, this issue
is really trivial to reproduce and verify:
```
apt-get install disorderfs
mkdir disorderedWorkspace/
disorderfs --shuffle-dirents=yes workspace/ disorderedWorkspace/
```
... then just build `samples/hello_world/` twice in disorderedWorkspace/
with any --board and compare the build directories.
