06c5e27080 Fix for GCP MTU size 
- This fix is specifically for Google Cloud Platform (GCP) VMs.
  The default MTU size on GCP, 1460 bytes, could cause network issues
  such as "cannot open websites" with IKEv2 VPN clients.
  This issue was brought up multiple times in this repo, e.g. #1000.
- The fix changes the MTU to 1500 (the default that is widely used),
  and updates dhclient.conf so that it is not reverted to 1460 by DHCP.

a0409b4399 Cleanup 
- In rare cases, if a parent process traps SIGPIPE, the 'tr'
  command in the VPN setup scripts could output an error
  'tr: write error: Broken pipe'. This is a cosmetic error
  that does NOT affect the functionality of the scripts. This
  commit hides the error in such cases.
