Shellcheck compliance

Browse source 
scripts/openvpn/makeOVPN.sh
 * SC1090: ShellCheck can't follow non-constant source. Use a directive to specify location.
  * Disabled warning
 * SC2086: Double quote to prevent globbing and word splitting.
  * Added missing double quotes
 * SC2001: See if you can use ${variable//search/replace} instead.
  * Disabled warning, suggested method doesn't go well with regexp
 * SC2154: <VarName> is referenced but not assigned.
  * Disabled warning, variables are sourced externally and may differ
