wiggle: add depends on groff-native
wiggle: add depends on groff-native

To fix, on sparse build hosts:

	nroff -man wiggle.1 > wiggle.man
	/bin/sh: 1: nroff: not found
	Makefile:41: recipe for target 'wiggle.man' failed

Tested by removing /usr/bin/nroff from my build host to ensure
(a) the error was seen and (b) the one in the sysroot was found
and used after making the change.
