DistributedLzoIndexer should treat input paths as globs

[gerashegalov]

It would be handy to be able to abbreviate a list of directories by a glob, e.g.:

hadoop  com.hadoop.compression.lzo.DistributedLzoIndexer '/logs/2014/12/01/{04,05}'

While we are at it, we should also enable a default path filter to skip hidden paths starting with '_' or '.' . We have a case where there could be a special directory with corrupted files that should be fixed.
