Subject: [PATCH 2/2] ir-lv2: remove mainProgram

The mainProgram was set in a treewide effort but does not actually
reflect the main program.

From
https://github.com/NixOS/nixpkgs/blob/master/pkgs/README.md#meta-attributes:

meta.mainProgram must be set to the name of the executable which
facilitates the primary function or purpose of the package.

Packages which are not primarily used for a single executable do not need to set meta.mainProgram.
