Fix install.sh script if curl is not present (#414)

Browse Source 
At least with bash 5.0.18, GNU Wget 1.20.3 and GNU Awk 5.1.0 the wget installation methods fails because the awk regex does not match the location header. In these versions, instead of `/^  Location:...` it must be `/^Location:...`. In order to retain compatibility with other versions having a different behavior, I changed it to `/^\s*Location:...`.
