Subject: [PATCH] sched: fix musl libc build

This commit solves the following error when building with musl libc
```
src/sched.c:34:17: error: 'sigset' redeclared as different kind of symbol
 static sigset_t sigset;
                 ^~~~~~
In file included from src/sched.c:21:0:
/usr/include/signal.h:231:8: note: previous declaration of 'sigset' was here
 void (*sigset(int, void (*)(int)))(int);
        ^~~~~~
make: *** [<builtin>: src/sched.o] Error 1
make: *** Waiting for unfinished jobs....
```

Based on the patch by @E100Beta
