Refactor: libcrmcluster: Drop crm_proc_DAEMON crm_proc_flags values

These are internal, so nothing external can get or set them except as
integers (in other words, they can't be set by their enum value names
anyway). Furthermore, internal functions only ever set crm_proc_none and
crm_proc_cpg.

The only thing that uses these values at all is proc2text(). This commit
removes those uses.
