[Meson] Apply work-around for gtest-related failure on meson 0.50.1

In the case that gtest has been installed via apt (i.e., apt install
libgtest-dev), meson provides the -I options indicating the directory
that does not exist. Therefore, it is failed to build when
'-Wmissing-include-dirs' is set. This patch works around this issue.
