mmbackup does not handle EXCLUDE.DIR rules preferentially over EXCLUDE rules

The TSM BA client dsmc by default includes everything in the backup domain (defaults to all local filesystems), optionally allowing one to exclude paths and even re-include paths that would by excluded by previous rules. There are two mechanisms for excluding paths within a filesystem:

EXCLUDE
EXCLUDE.DIR

The latter only works with directories, but paths that are excluded with EXCLUDE.DIR can never be re-included, while paths excluded with EXCLUDE can be re-included. For instance, this would support a default-exclude policy for a filesystem, include home directories, and also allow users to create directories called "nobackup" anywhere in the gpfs1 filesystem and have them excluded from backups, even if they're in home directories:

EXCLUDE.DIR nobackup
INCLUDE /gpfs/gpfs1/home/.../*
EXCLUDE /gpfs/gpfs1/.../*

Unfortunately, while this would work with the native TSM BA client, mmbackup treats EXCLUDE.DIR the same as EXCLUDE and will actually include all paths underneath /gpfs/gpfs1/home even if they're called "nobackup".

The RFE would involve updating mmbackup include/exclude rule processing to match the handling with the TSM BA client.
