app-text/podofo: migrate to lua-single.eclass

CMake-based => the usual treatment.

Compatibility - upstream officially supports only lua5.1 but it turns out
that with the 5.2 fix which was already included in the unmigrated ebuild,
it builds and installs fine even against 5.4.

Closes: https://bugs.gentoo.org/752567
