Subject: [PATCH] libdnf: Fix arm arch mapping issues for qemuarmv5

We change the way rpm architectures work, we make the machine name the default machine
specific package architecture.

This arm mapping code can work or in the case of qemuarmv5, it doesn't as it creates
armv5hl which doesn't exist and causes errrors. We can simply remove it, we don't need it.

Upstream-Status: Inappropriate [Relies on OE rpm config]
