sysklogd: add patch to fix build with glibc 2.24

Building sysklogd with glibc 2.24 fails with the following error:

syslogd.c: In function ‘reapchild’:
syslogd.c:2097:13: error: storage size of ‘status’ isn’t known
  union wait status;
             ^
Makefile:99: recipe for target 'syslogd.o' failed
make[2]: *** [syslogd.o] Error 1
make[2]: *** Waiting for unfinished jobs....
package/pkg-generic.mk:201: recipe for target './buildroot/output/build/sysklogd-1.5.1/.stamp_built' failed
make[1]: *** [./buildroot/output/build/sysklogd-1.5.1/.stamp_built] Error 2
Makefile:41: recipe for target '_all' failed
make: *** [_all] Error 2

union wait was marked deprecated in glibc 2.23 and removed in glibc 2.24.
The fix is to declare it as an int.
