Subject: [PATCH] action.c: add _POSIX_C_SOURCE

...to compile cleanly with musl on Void Linux and avoid:

```
[9/58] Compiling C object labwc.p/src_action.c.o
../src/action.c: In function 'actions_run':
../src/action.c:204:4: warning: implicit declaration of function 'kill' [-Wimplicit-function-declaration]
  204 |    kill(getpid(), SIGHUP);
      |    ^~~~
[58/58] Linking target labwc
```
