meson: Drop required libfdisk version to 2.32

We initially pinned this to 2.33 in
e71f5585b9b0580428f9530d0a485265c9c25165 because libfdisk 2.32 in

(https://git.centos.org/rpms/util-linux/blob/c8s/f/SOURCES/0048-libfdisk-count-gaps-to-possible-size-when-resize.patch)
which means we can drop the required version to 2.32 instead of 2.33.
