Base.julia_cmd() should propagate `--inline=no`

It currently doesn't:
```jl
bash$ julia --quiet --inline=no
julia> Base.julia_cmd()
`/Users/stefan/projects/julia/usr/bin/julia -Cnative -J/Users/stefan/projects/julia/usr/lib/julia/sys.dylib --compile=yes --depwarn=yes`
```
Propagating from the main Julia would be better than e.g. https://github.com/JuliaLang/Pkg.jl/pull/866.
