[installer] Fix variable inside machine.conf caused install.sh error (#6600)
Encounter error when install SONiC image if there are some onie_discovery variables assigned with multiple values inside machine.conf

- How I did it

Replace original ". /machine.conf" method and add another function to do the same thing.

- How to verify it

Add a item inside /host/machine.conf like onie_disco_ntpsrv=10.254.141.10 10.254.141.131
Do sonic_installer install to check if any error occurs
