sudo: drop 020-no-owner-change.patch for a make override

The patch blanked INSTALL_OWNER in Makefile.in so the staged install does
not chown to install_uid/install_gid, which fails when building as an
unprivileged user. sudo already supports this: the top-level install rule
recurses with "INSTALL_OWNER=$(INSTALL_OWNER)" into every sub-make, and
sudo's own "package" target does "make install INSTALL_OWNER=" for exactly
this fakeroot case. Pass INSTALL_OWNER= via MAKE_INSTALL_FLAGS instead of
carrying a patch.
