The libmount dependency in systemd was made optional upstream [2]. This
series backports that change, allowing us to drop util-linux as a build
dependency for systemd. This resolves a circular dependency between
util-linux and systemd when systemd PACKAGECONFIG is enabled in
util-linux. Without this fix, each recipe depends on the other,
triggering the circular dependency error.

Note that this alone does not fully resolve the circular dependency
on util-linux-fstrim/uuid. There is another one:

glib-2.0 -> util-linux -> systemd -> shared-mime-info -> glib-2.0

But the libmount PACKAGECONFIG can be removed from glib-2.0 to break its
dependency on util-linux.

In addition, according to systemd's README [2], the dependencies on
libblkid and libfdisk from util-linux are optional, so add them as new
PACKAGECONFIGs.

[2] https://github.com/systemd/systemd/blob/main/README#L216

v2:
- commit description updated on both patches.
- blkid set as default PACKAGECONFIG to fix an error where bootctl is
  not built anymore. See
