Cygwin: fix build failure due to redefinition of __restrict in sys/cdefs.h 

Commit 3c75fac130 fixed the __restrict definition in sys/cdefs.h,
but uncovered a problem in the definition of lio_listio in Cygwin's
aio.h.  It uses the C99 extension of using the restrict keyword
to define non-overlapping arrays. However, this is not allowed in
C++.

Use the newly defined __restrict_arr from commit e66c63be6b
("sys/cdefs.h: introduce __restrict_arr, as in glibc")

Fixes: 3c75fac130 ("sys/cdefs.h: fix for use __restrict in C++"
