feat: sendfile works with -m, error on -f + -c/-s

Browse Source 
- load_files_multithreaded skips file_load_data when sendfile is active
- -f + -m works: sendfile bypasses loader, sender uses sendfile directly
- -f combined with -c or -s prints error and exits with rc=1
- Add Sendfile + Multithreading test case
