spec: Work around a bug in ctest macro on RHEL 9

Building the RPM package on RHEL 9 failed like this:

    error: /builddir/build/originals/libdnf.spec: line 238: Unknown option V in ctest(:-:)

The failure was introduced with commit
a067e64 ("spec: Consistently use CMake
RPM macros"). The cause is a bug in a defintion of the ctest macro
provided with cmake-rpm-macros-3.26.5-2.el9.noarch by RHEL 9
<https://issues.redhat.com/browse/RHEL-120543>.

This patch works around the bug by redefining the macro while accepting
any options.
