www-servers/nginx: migrate to lua-single.eclass

http_lua only supports LuaJIT but even so, use the eclass helper
functions to find it.

Only migrated SLOT=mainline because as far as I could see there are no
nginx revdeps in the tree explicitly requiring SLOT=0.

Closes: https://bugs.gentoo.org/752879

+# Maintainer notes:
+# - http_rewrite-independent pcre-support makes sense for matching locations without an actual rewrite
+# - any http-module activates the main http-functionality and overrides USE=-http
+# - keep the following requirements in mind before adding external modules:
+#	* alive upstream
+#	* sane packaging
+#	* builds cleanly
+#	* does not need a patch for nginx core
+# - TODO: test the google-perftools module (included in vanilla tarball)
