Split the common part into a function, to be reused.

The tail call is optimized, meaning now mmin/mtime just prepare arguments
and jump into the common code, thus near zero overhead.

This reduces code size slightly, e.g. on x86_64:
   text    data     bss     dec     hex filename
   4806       0       0    4806    12c6 findutils/find.o.orig
   4782       0       0    4782    12ae findutils/find.o

Of course, the savings are even greater when implementing atime/ctime
variants.
