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.
