Split up each option value properly.

"evm:db:region --" was previously intended as a single unescaped option key with no value.

AwesomeSpawn was changed to escape keys in addition to values that it had done previously.
This caused the command line to be built like this:
script/rails runner script/rake evm:db:region\ -- --region 0

"dvm:db:region" and "--" are now separate option values with no key.
Change to AwesomeSpawn instead of using LinuxAdmin.
Split up a long line for readability.
