Fix redirection of read when _FORTIFY_SOURCE is defined

Browse source 
When _FORTIFY_SOURCE is defined mingw-w64 provides an inline definition
of read in io.h.  This makes our previous redirection to sys_read
ineffective.  The prototype of sys_read is now required because we don't
touch the prototype of read.

* nt/inc/ms-w32.h (read): Move the redirection after io.h.  Add prototype
for sys_read (Bug#73444)
