autofs-5.1.8 - add missing include to log.h for pid_t
Fixes build failures on musl like:
```
../include/log.h:49:8: error: unknown type name 'pid_t'
49 | extern pid_t log_pidinfo(struct autofs_point *ap, pid_t pid, char *label);
| ^~~~~
../include/log.h:49:51: error: unknown type name 'pid_t'; did you mean 'gid_t'?
49 | extern pid_t log_pidinfo(struct autofs_point *ap, pid_t pid, char *label);
| ^~~~~
| gid_t
```
