Revert "package/libbluray: add optional support for libudfread"

This reverts commit 7aa9b9041d29547114d29f963d567fe421cccb1b.

libbluray before 1.3.0 does not properly detect libudfread, because it
checks for the incorrect name (it asks pkg-config for udfread instead of
libudfread). So, even with the dependency, it would miss it.
