meson.build: defaults for "build.c_std" and "build.cpp_std"

Since Meson 0.51, there are special build options for "native:true" builds, prefixed with "build.". This change breaks cross builds because `GenParseName.cxx` is no longer built with `-std=c++17`. This patch adds defaults for "build.c_std" and "build.cpp_std". Closes https://github.com/MusicPlayerDaemon/MPD/issues/890
