Remove the arch-based filtering hack in packaging.go

aosp/1501613 has landed. The filtering hack is no longer needed.

Also, fixed a bug that the dependency to the dynamic linker is not
treated as install dep.

Bug: N/A
Test: `m hosttar` and compare the built cvd-host_package.tar.gz with and
without this change. There is no removed file.
