meson: explicitly mark run_command as fallible when returncode is checked

Meson emits a warning stating that the default will change from false to
true, in some future version, and that one should always pass
`check: BOOL` explicitly. Normally this is because commands that
unexpectedly fail would result in wrong behavior if the build treats it
as though it succeeded.

In this case, we were specifically relying on it being `check: false`,
as the returncode is immediately checked in order to provide a better
error message. Make this explicit in the meson.build file.
