largefiles: replace always() method, not _always field
We will soon have matchers that don't have an _always field, so
largefiles needs to stop assuming that they do. _always is only used
by always(), so we safely replace that method instead.

grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory" | \
