Use KF_PATH to verify the size of a struct kinfo_file.
fbsd_core_vnode_path needs to use the offset of the kf_path member of struct kinfo_file as the minimum size of a struct kinfo_file object. However, it was using KVE_PATH instead due to a copy and paste bug. While here, fix another copy and paste bug in the error message for a truncated kinfo_file object. gdb/ChangeLog: * fbsd-tdep.c (fbsd_core_vnode_path): Use KF_PATH instead of KVE_PATH.
