meson: perform snappy test with the C++ compiler if used
Snappy is written in C++ and as such needs to link against libstdc++. When
linking statically, this means that the compile test cannot succeed unless
performed with a C++ compiler. Do so if link_language is set to C++; if it
is C, the test will usually fail and snappy will be disabled.
