    Mk/bsd.gecko.mk: switch LLVM to 17
    
    This brings gecko ports in line with rust's embedded llvm for those
    who want to try LTO. It also seems to improve overall behaviour
    of gecko ports, based on single-installation experience.
    
    (cherry picked from commit 5c53f4de1a915eccf9f05932c48bf459a4e936d6)
