src/sulogin.c: Remove 'static' from a temporary variable

There's no need to keep 'pass' in .bss:

$ grep -nC3 '\<pass\>' src/sulogin.c
58-/*ARGSUSED*/ int main (int argc, char **argv)
59-{
60-	int     err = 0;
61:	char    pass[BUFSIZ];
62-	char    **envp = environ;
63-	TERMIO  termio;
64-#ifndef USE_PAM
--
166-#endif
167-			exit (0);
168-		}
169:		STRTCPY(pass, cp);
170-		erase_pass (cp);
171-
172:		if (valid (pass, &pwent)) {	/* check encrypted passwords ... */
173-			break;	/* ... encrypted passwords matched */
174-		}
175-
176-		sleep (2);
177-		(void) puts (_("Login incorrect"));
178-	}
179:	MEMZERO(pass);
180-	(void) alarm (0);
181-	(void) signal (SIGALRM, SIG_DFL);
182-	environ = newenvp;	/* make new environment active */
