Docker: build Session::Token with C17
The image build failed at the dependency installation. Session::Token declares
the functions of its bundled isaac implementation without prototypes, which is
an error since alpine moved to a gcc that defaults to C23:
Token.xs:31:7: error: too many arguments to function 'isaac'; expected 0, have 1
It comes in through Mojolicious::Plugin::Util::RandomString, so nothing works
without it. Only this one distribution is built with C17, everything else keeps
the defaults. CI is not affected, its gcc still defaults to C17.
The image builds again and serves the example model: paradigmatic and
syntagmatic neighbours, count based collocators and getVecsByRanks all return
the expected results.

- Devel::CheckLib, which `Makefile.PL` needs to find libcollocatordb before it
