More NSS fixes for macOS on arm64

I think the attempt to set CPU_ARCH in
external/nss/ExternalProject_nss.mk does not actually work. And
anyway, it should be arm64 for macOS on arm64, not aarch64.

Now NSS configury correctly finds the APIs present in the system when
building for macOS on arm64. Previously, it attempted to compile the
test snippets for PowerPC... which caused for instance dladdr() not to
be found, which caused the softokn3 loading to fail.

(It's somewhat surprising that the NSS configury still has "support"
for MacOS on PowerPC... Do people really build latest and greatest NSS
on such machines? Or is it just a leftover and the NSS people never,
ever, remove anything?)
