net-libs/axtls: migrate to lua-single.eclass

axtls in cgi-lua mode simply executes the Lua interpreter so a) it can
support all Lua implementations currently in the tree, and b) all we have
to do at build time is substitute /usr/bin/lua with ${LUA} in .config.

+# axtls CONFIG MINI-HOWTO
+#
+# Note: axtls is highly configurable and uses mconf, like the linux kernel.
+# You can configure it in a couple of ways:
+#
+# 1) USE="-savedconfig" and set/unset the remaining flags to obtain the features
+# you want, and possibly a lot more.
+#
+# 2) You can create your own configuration file by doing
+#
+#	FEATURES="keepwork" USE="savedconfig -*" emerge axtls
+#	cd /var/tmp/portage/net-libs/axtls*/work/axTLS
+#	make menuconfig
+#
+# Now configure axtls as you want.  Finally save your config file:
+#
+#	cp config/.config /etc/portage/savedconfig/net-libs/axtls-${PV}
+#
+# where ${PV} is the current version.  You can then run emerge again with
+# your configuration by doing
+#
+#	USE="savedconfig" emerge axtls
+#
