Skip execution of Julia startup file when checking for envdir

[sorokod]

The change to getEnvDir() is implemented using a non interactive call to Julia ( -E ) and required a change for executeCommand to accept multiple arguments.

I bumped my local Kotlin version to 1.4 to avoid the error here ...available since Kotlin 1.4 and cannot be used in Kotlin 1.3 but the error has nothing to do with a change in this PR.

@ice1000 , does master builds for you with 1.3 ?
