refactor(fileio): remove useless use of FileDescriptor

FileDescriptor is used to buffer togheter many small writes to fewer
syscalls. if the data to write already is in a single buffer, it is
perfectly fine to just use os_write directly (which will take care of
the reverse problem: splitting a too big write into many syscalls)
