Ubuntu pg_config packaged a bit differently, and required libraries
actually can be found in pkglibdir. Search anyway for libdir, then
pkglibdir. Another catch is that pg_config add a new line at the end,
which breaks stuff, so strip it.
Build seems to fail with PostgreSQL 12 version, due to incompatibility
after [1], and required presence of libpgport (to expose pg_sprintf for
scram implementation).
To improve the situation, introduce couple of changes:
* Rely on pg_config to get lib/include directories
* Add libpgport.a into linking
* Provide different versions of pg_b64_decode/encode depending on
PG_VERSION_NUM
