Subject: signal.c: Use MINSIGSTKSZ by casting to int

MINSIGSTKSZ is unsigned int in OpenBSD, which makes a warning of
comparison:

```
signal.c:535:14: warning: comparison of integers of different signs: 'int' and 'unsigned int' [-Wsign-compare]
    if (size < MINSIGSTKSZ)
        ~~~~ ^ ~~~~~~~~~~~
1 warning generated.
