rogue5: ignore the file name stored in the save file.
state.c had put file_name into the save file. The saved value was used
to overwrite file_name on restore. If the save file had been renamed,
unlink(file_name) would then fail, because file_name held the old name.
To avoid breaking savefile compatibility, file_name is still saved, but
it is read back into a temporary buffer and then ignored.
I thought I fixed this already.
