UNIXProcess_md.c: do not retry EINTR failed close() calls

If close() return EINTR, the file descriptor _will_ have been closed. The
error return just tells you that soem error happened on the file: for
example, in the case of EINTR, the close() may not have flushed all the
pending data synchronously.
Re-doing the close() is the wrong thing to do, since in a threaded
environment, something else might have opened another file, gotten the
same file descriptor, and you now close _another_ file.
