Build FIPS package via build-cmk-distro-package

trigger-cmk-distro-package was added on master/2.5.0 in CMK-26121 but
never reached 2.4.0, so the FIPS package build stage added in 26e5588
crashed with "No job ... trigger-cmk-distro-package found". Use the
existing build-cmk-distro-package job, like the non-FIPS path does.
