configure: Apply -Werror=vla to C++ as well as C

The comment part of d9dd406fe281 mentioned that -Wvla is not applicable
for C++. That is not fully correct: it is true that VLAs are not part of the
C++ standard, and g++ with -pedantic will also warn about them as a non-standard
extension. However, -Wvla itself works fine in C++ and will catch VLA
usage just as in C.

Fix configure.ac to apply -Werror=vla to C++ as well. There is no need to
fix meson.build as it already includes it in common_warning_flags.
