iptables: increment PKG_RELEASE to force update

While support for the FLOWOFFLOAD target is available in the firmware
images, it is still missing in some of the binary packages on
downloads.openwrt.org, e.g. for the mipsel_mips32 architecture.

Increment PKG_RELEASE to force an update of these packages.
Also adjust the package description to include the FLOWOFFLOAD target.
