Mario Fetka 9ab65e2f00 dosutils: add RIGHTS and finish Novell-style display fixes
- add RIGHTS as a new multi-call DOS utility
- implement Client32 NCP87 effective-rights query helper
- map NCP effective-rights bits to Novell RIGHTS display order
- keep legacy directory-handle based rights lookup as fallback
- match Novell RIGHTS output for directories and files more closely
- remove hardcoded MARS/SYS and SYS display fallbacks from RIGHTS/FLAGDIR
- derive display prefixes from the active network drive where available
- adjust FLAGDIR output formatting to match Novell field alignment
- keep FLAG and SLIST unchanged after checking for hardcoded prefixes
