Add some const qualifiers

There was a mismatch between the const qualifiers for
excludeDirContents in src/backend/backup/basebackup.c and
src/bin/pg_rewind/filemap.c, which led to a quick search for similar
cases.  We should make excludeDirContents match, but the rest of the
changes seem like a good idea as well.
