resindvd: Remove local basesrc copy

Browse source 
Use the real version of basesrc instead of a local copy now that it
supports the seamless segment feature that resin needs.

* @get_size: Return the total size of the resource, in the configured format.
* @is_seekable: Check if the source can seek
* @unlock: Unlock any pending access to the resource. Subclasses should
* unblock any blocked function ASAP
* @unlock_stop: Clear the previous unlock request. Subclasses should clear
* any state they set during unlock(), such as clearing command queues.
* @event: Override this to implement custom event handling.
* @create: Ask the subclass to create a buffer with offset and size.
* @do_seek: Perform seeking on the resource to the indicated segment.
* @prepare_seek_segment: Prepare the GstSegment that will be passed to the
* do_seek vmethod for executing a seek request. Sub-classes should override
* this if they support seeking in formats other than the configured native
* format. By default, it tries to convert the seek arguments to the
* configured native format and prepare a segment in that format.
* Since: 0.10.13
* @query: Handle a requested query.
* @check_get_range: Check whether the source would support pull-based
* operation if it were to be opened now. This vfunc is optional, but
* should be implemented if possible to avoid unnecessary start/stop
* cycles. The default implementation will open and close the resource
* to find out whether get_range is supported, and that is usually
* undesirable.
* @fixate: Called during negotiation if caps need fixating. Implement instead of
* setting a fixate function on the source pad.
*
* Subclasses can override any of the available virtual methods or not, as
* needed. At the minimum, the @create method should be overridden to produce
* buffers.
