MIPS fallocate fixes

Subject: MIPS fallocate fixes

In <http://sourceware.org/ml/libc-ports/2009-05/msg00028.html> I added
the exports of the fallocate64 symbol for MIPS.  n32 and n64 still
need fixes to use the 64-bit syscall interface for fallocate and
fallocate64, just as in my patch
<http://sourceware.org/ml/libc-ports/2008-12/msg00007.html> for
posix_fallocate and posix_fallocate64; I've applied this patch to add
appropriate versions for n32 and n64.

(It is certainly possible other syscalls still need fixes for n32 or
n64, especially if the wrappers are not tested by the glibc
testsuite.)
