[Toybox] [PATCH] find.c: don't assume time_t is the same as long

[Rich Felker]

I did this with a cast to long long rather than intmax_t since I think
you prefer long long, but either should be fine. This incurs a slight
binary size cost on 32-bit targets with 32-bit time_t (glibc, uclibc,
old musl) that could be eliminated via a conditional of the form:

	if (sizeof(time_t)>sizeof(long))
		/* print by casting to long long */
	else
		/* print by casting to long */

but I would prefer not uglifying the code over saving a couple bytes
of binary.

This is false on ILP32 targets with 64-bit time_t.
