package/systemd: fix bcachefs magic patch

Commit 29409c9d34 ("package/systemd: fix
build with recent kernels") added a patch from upstream that adds the
BCACHEFS_SUPER_MAGIC definition if not provided by the kernel headers.

However, this commit from upstream was bogus: in the case
BCACHEFS_SUPER_MAGIC was defined, it does an assert_cc() to verify
that the value matches what we expect, but this assert_cc() statement
lacks the final semi-colon, causing build breakage on host systems
that do have BCACHEFS_SUPER_MAGIC defined in their kernel headers,
with a weird error occuring in another header file... because only the
next statement after assert_cc() was considered as having a syntax
error.

Fixes:

  http://autobuild.buildroot.net/results/9f99a97df2efd5e4ae4ad5cc5882607f0c8766bc/

This issue only exists in 2024.02.x at this point, because in master
we have moved to systemd 256.x, which has dropped entirely this piece
of code related to defining BCACHEFS_SUPER_MAGIC (and we wonder how
systemd can then build with slightly older kernel headers, as
BCACHEFS_SUPER_MAGIC is only in the public kernel headers since Linux
6.10).
