Add sol2 to wrapdb

Local sanity checks fails with this error, so I will debug via CI :(

aserebriyskiy@i113824053:~/Dev/wrapdb$ ./tools/sanity_checks.py 
setUpClass (__main__.TestReleases) ... ERROR

Also, meson setup builddir -Dwraps=sol2 totally ignores my provided meson.build and uses one from project, which is unfortunate :(
