COPR not skipping builds with ExcludeArch after ExclusiveArch

[tstellar]

I ran into this issue building the retsnoop package in COPR. The ppc64le build is not skipped, even though the architecture is excluded in the spec file. I think it may be because the spec uses both ExclusiveArch and ExcludeArch, like this:

ExclusiveArch:  %{rust_arches}
# bpftool not compiling on ix86
# we don't ship 32-bit binaries anyway, but it'd be good to test compilation
# once this is fixed https://github.com/libbpf/bpftool/issues/158
ExcludeArch:    %{ix86}
# retsnoop 0.11 FTBFS on ppc64le
# rhbz#2402550
ExcludeArch:    ppc64le

Hedgewars is another example of this problem.
