[runtimes] Name stripped install targets consistently

[smeenai]

Summary

We were previously naming sub-component stripped install targets as
install-${component}-stripped-${triple}, whereas everywhere else names
them install-${component}-${triple}-stripped. This inconsistency would
cause issues when LLVM_RUNTIME_DISTRIBUTION_COMPONENTS contained a
sub-component (which I'm addding support for next).
