ci: adapt to 'dtrace' package split

Fedora has decided to separate dtrace out of the systemtap-sdt-devel
package: https://fedoraproject.org/wiki/Changes/Separate_dtrace_package

Similarly, these are split in OpenSUSE Tumbleweed, however in a
backward-compatbile way:
https://build.opensuse.org/package/show/openSUSE:Factory/systemtap

Require the new 'systemtap' package mapping, as well as the old
'dtrace'.
