[PATCH v1 1/2] apps: cam: capture_script: Disallow arrays of strings

The current `ControlValue` mechanism does not support arrays
of strings, the assignment in the removed snippet will in fact
trigger an assertion failure in `ControlValue::set()` because
`sizeof(std::string) != ControlValueSize[ControlTypeString]`.
