work around the dnf5 issue when --skip-broken is not recognized
The SELinux beaker library calls the yum/dnf command and the
"--skip-broken" option is placed before the "install" word on the
command line. Such command line executed on Fedora rawhide leads to
the following error message:
Unknown argument "--skip-broken" for command "dnf5". Add "--help" for
more information about the arguments.
In order to work around this issue, the "install" word was moved before
the rest of options. Manual testing revealed that this approach works
on Fedora rawhide.
