Allow OPM installation with newer lua-resty-http versions.

The "pintsized/lua-resty-http" git repo was renamed to
"ledgetech/lua-resty-http" for the 0.13 release:
https://github.com/ledgetech/lua-resty-http/commit/f71e9708a3fd0ff4179d4b0d770c91fcf98d0042#diff-a580a87ff9da14b51504d149be8ecaff
The repo now also redirects from "pintsized" to "ledgetech" on
github.com: https://github.com/pintsized/lua-resty-http

This switches the dependency to the new repo name. Without this, you
can't install lua-resty-openidc if you already have the newer
"pintsized/lua-resty-http" package installed, due to package conflicts.
