timegm.m4 simplification

[Bruno Haible]

Hi Paul, Jim,

> True.  Good change.  That's obviously correct.

A similar one is here. 'timegm' depends on 'time_r' as a module, therefore
I'm applying this:

        timegm: Simplify autoconf macro.
        * m4/timegm.m4 (gl_PREREQ_TIMEGM): Don't require gl_TIME_R.
