Extracting information for rpm archives on Solaris is failing.

This is mainly due to the fact that long argument names are being used with
cpio within fr-command-rpm.c, and long argument names are not supported on the 
version of cpio delivered with solaris, which is not the gnu version.

Swithching the hard coded arguments to their short equivalents fixes this.

e.g.
	change :
		cpio --list --force-local --verbose
	to
		cpio -i -t -v
	
	also change
		cpio --extract --force-local --unconditional --make-directories
	to
		cpio -i -u -d

The list processing also needs to change slightly as cpio on solaris verbose
listing outputs one extra field, the time of last modification.
