Add '--always' to vcs_tag in meson.build

[ComfyKernel]

Without it there is a chance that the build will fail because git couldn't generate a full version name.

change

> ['git', 'describe' '--dirty=+']

to

> ['git', 'describe', '--always', '--dirty=+']

Hi, I actually didn't write this, I adapted dxvk's build scripts.

Is there a reason why this only affects dxup and the same doesn't apply to dxvk?

It's possible this also affects DXVK, I just haven't had the need to build it in a long time since it's distributed on steam and in winetricks

Looked into this more, added it.
Seems like it's needed when nothing is tagged.

Cheers!
