Inconsistency between RPM requires and provides after cmake modernization

After lhcb/LHCb!2931 (merged) (and matching ones) the RPMs are generated with requires like:

LHCB_53.0_x86_64_v2_centos7_clang11_opt

but the provides are like:

LHCB_v53r0_x86_64_v2_centos7_clang11_opt

causing dependencies resolution problems in lbinstall.
