Subject: Fix <time.h> check
MIME-Version: 1.0

We're conditionally including based on HAVE_TIME_H in a bunch of places,
but we're not actually checking for time.h, so that's never going to be defined.

While at it, add in a missing include in the cram plugin.

This fixes a bunch of implicit declaration warnings:
```
 * cyrus-sasl-2.1.28/lib/saslutil.c:280:3: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
 * cyrus-sasl-2.1.28/lib/saslutil.c:364:41: warning: implicit declaration of function ‘clock’ [-Wimplicit-function-declaration]
 * cyrus-sasl-2.1.28/plugins/cram.c:132:7: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
 * cyrus-sasl-2.1.28/lib/saslutil.c:280:3: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]

 * cyrus-sasl-2.1.28/plugins/cram.c:132:7: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
```
