[PATCH v3] meson: Use -fno-sanitize=function when available

[Akihiko Odaki <akihiko.odaki@daynix.com>]

Commit 23ef50ae2d0c (".gitlab-ci.d/buildtest.yml: Use
-fno-sanitize=function in the clang-system job") adds
-fno-sanitize=function for the CI but doesn't add the flag in the
other context. Add it to meson.build for such. It is not removed from
.gitlab-ci.d/buildtest.yml because -fno-sanitize=function in meson.build
does not affect --extra-cflags due to argument ordering.
