populate_sdk_ext: use SDK_CUSTOM_TEPLATECONF variable to enable custom templateconf.cfg

The current implementation will always pick an existing templateconf.cfg if
present else it will use the one from OE.  A user might not always want to pick
an existing tempalteconf.cfg even if its present.  Introduce
SDK_CUSTOM_TEMPLATECONF variable to provide an option for the user to specify if he
wants to use an existing custom templateconf.cfg or not

If SDK_CUSTOM_TEMPLATECONF=='1' then enable custom templateconf.cfg. By default
SDK_CUSTOM_TEMPLATECONF is set to '0'
