[Buildroot] [git commit branch/2018.11.x] package/meson: never try to run generated target binaries

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=ae31ce3cde74db8c9e0fae6a7701036c49bfe7b1
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.11.x

As explained in [0], meson will try on its own to decide whether it can
run what it builds. If it happens that the host and target CPUs are
"compatible", that test may fail and meson may believe it can run what
it builds.

Override that test by using needs_exe_wrapper=true, and not defining an
actual exe_wrapper.
