lcdproc: remove patch rejected upstream

Remove an lcdproc patch which has been rejected upstream. It has been
decided by lcdproc developer Markus Dolze that the behaviour of the
client_add_key command when handling the minus key is "intentional to
some degree."

This patch also takes the opportunity to remove the version number from the
single remaining lcdproc patch.
