package/systemd: fix build with recent kernels

Browse Source 
Backport a patch from upstream that adds the magic number for the
bcachefs superblock. Otherwise, systemd 254.13 fails to compile with
the latest kernel versions.

Subject: [PATCH] basic: Add BCACHEFS magic
Import magic.h from Linux 6.9 to get the definition of
BCACHEFS_SUPER_MAGIC. Update filesystems-gperf.gperf to add knowledge of
bcachefs.
This fixes the following error building against a bleeding edge kernel.
```
src/basic/meson.build:234:8: ERROR: Problem encountered: Unknown filesystems defined in kernel headers:
Filesystem found in kernel header but not in filesystems-gperf.gperf: BCACHEFS_SUPER_MAGIC
```
