libdnf: Fix arm arch mapping issues for qemuarmv5

qemuarmv5 currently fails with:

$ dnf --help
Error: Incorrect or unknown "arch": armv5hl

Fix this by removing the code in libdnf which is trying to be too
clever, we don't need this mappings given the way OE configures rpm.

+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.
