cmd/internal/obj: shrink Prog, remove two unused fields

Printed and Width were unused. Despite only removing two bytes, due to alignment, 8 bytes are saved on 64-bit: Before: unsafe.Sizeof(obj.Prog{}) == 304 After: unsafe.Sizeof(obj.Prog{}) == 296 The next size class below 320 (304=>19(320)) is 288. Still 8 bytes away from that.
