fclose bug causes hang in nonthreaded apps

[Paul Brook]

I'm seeing a hang in applications that open and close files with a 
non-threaded uClibc.  There is code in fclose() to remove a file handle from 
_stdio_openlist however it's commented out, allegedly because it is dead.
_stdio_openlist is used in several places, including _stdio_term when a 
program exits. fclose() frees the struct, so I don't see how the code can 
possibly be redundant.

In the __UCLIBC_HAS_THREADS__ && __STDIO_BUFFERS case the file is removed from 
_stdio_openlist by __STDIO_OPENLIST_DEC_USE.

The attached patch fixes this bug be re-enabling the code.
