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

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=f112f2b991b47a7309116e132c969e3731a7e911
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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.
