package/eudev: remove obsolete --disable-introspection configure flag

It was removed from eudev with version 1.5.1, when introspection
became part of the gudev option [1]. This has in turn been removed and
replaced by package/libgudev, yet somehow the flag stayed. Remove it
to remove a warning during configure stage.
