fix: rollback xfsprogs to 5.18.0

Rollback xfsprogs to 5.18.0.

Talos [state partition](https://github.com/siderolabs/talos/blob/main/internal/pkg/partition/constants.go#L37) uses a 100MiB partition size of xfs type. Since xfsprogs 5.19.0 paritions of size less than 300MiB are not allowed. For now it doesn't make sense to increase the Talos `STATE` partition size from 100MiB to 300MiB just to make it work with newer xfsprogs. Until Talos has a use case for larger `STATE` partition or a different filesystem type for `STATE` partition, keep xfsprogs locked to `< 5.19.0` allowing minor fixes if any.

From the xfsprogs [code](https://fossies.org/linux/xfsprogs/mkfs/xfs_mkfs.c):

```text
 2523     /*
 2524      * We don't support filesystems smaller than 300MB anymore.  Tiny
 2525      * filesystems have never been XFS' design target.  This limit has been
 2526      * carefully calculated to prevent formatting with a log smaller than
 2527      * the "realistic" size.
 2528      *
 2529      * If the realistic log size is 64MB, there are four AGs, and the log
 2530      * AG should be at least 1/8 free after formatting, this gives us:
 2531      *
 2532      * 64MB * (8 / 7) * 4 = 293MB
 2533      */
