Fedora: stabilize tests for Rawhide

We have a bunch of needed fixes for Fedora testing (and 1minutetip, too).

• use arch instead of uname -p as broken showing unknown in Rawhide
• remove workaround (mainly installations) and clean up installation scripts too
• make vethsetup and default profile connected more robust
• add EDITOR=vim to nmtui so we can easily run json tests
• add generic fedora tests file to be used (no version anymore)
• stabilize libreswan tests setup and teardown
• DNS tests were failing with resolved due to error in reading /run/systemd/resolve/
• dump_status output now has resolved output if present
• let strongswan's charon to autoload modules
