 Twenty Fourteen: Fix fatal errors in WordPress versions before 4.0.0

 The line of code throwing the error was introduced in WordPress 4.5 in
 r37040 "Customize: Require opt-in for selective refresh of widgets". Since
 `is_customize_preview()` was introduced in 4.0.0 and Twenty Fourteen
 should work from WordPress 3.6 and up, this caused the issue.

 The patch adds an `is_customize_preview` function if it's missing.

 Props adamsilverstein.

 Fixes #39407.
