[PULL 15/17] meson: Mingw64 gcc doesn't recognize system include_type for sdl2

[Paolo Bonzini]

From: Yonggang Luo <luoyonggang@gmail.com>

Windows paths result in command lines like "-isystemC:/msys64/..." that
are not recognized by GCC.  "include_type: 'system'" was only included
in an attempt to fix the -Wundef warnings in SDL 2.0.8, but it was not
effective.  Therefore we can fix this by remove the include_type.
