builder.sh: check if variable is non null

Browse Source 
This is not the "correct" way to check if a variable is non null in
bash. There is already an instance of the "right" way to do it in
setup.sh. Bash is "generous" enough to accept the original input though.
I couldn't find the relevant shellcheck.
