    perf: disable BUILD_BPF_SKEL
    
    BUILD_BPF_SKEL was set to 1 by default in upstream commit:
    9925495d96efc14d885ba66c5696f664fe0e663c ("perf build: Default
    BUILD_BPF_SKEL, warn/disable for missing deps")
    
    Prior to that, it was disabled by default and you had to enable it to
    build BPF skeleton support.
    
    So in order to fix perf compilation with kernel 6.12, lets disable
    BUILD_BPF_SKEL.
    
    Fixes: #19310
