amd64/ramdisks/common/list.ramdisk.
Previously, the amd64 list.ramdisk used the small version of gzip from
distrib/utils/x_gzip, while the i386 list.ramdisk used the full version
of gzip built from usr.bin/gzip, and also used extra libraries needed to
make that work. Now, they both use the small version.
The only other difference was in the order of some PROG lines.
