block/meson.build: Restore alphabetical order of files

When commit 5e5733e5999 created block/meson.build, the list of
unconditionally added files was in alphabetical order. Later commits
added new files in random places. Reorder the list to be alphabetical
again. (As for ordering foo.c against foo-*.c, there are both ways used
currently; standardise on having foo.c first, even though this is
different from the original commit 5e5733e5999.)
