func_dialplan: Remove deprecated/redundant function.

Browse Source 
Remove VALID_EXTEN, which was deprecated/superseded by DIALPLAN_EXISTS
in Asterisk 11 (commit 8017b65bb9),
as DIALPLAN_EXISTS does the same thing and is more flexible.

Resolves: #1347

UpgradeNote: The deprecated VALID_EXTEN function has been removed.
Use DIALPLAN_EXISTS instead.
