    linux-yocto/rt: enable kprobes by default

    Traditionally kprobes and -rt haven't mixed well, but recent -rt
    kernels support kprobes without issues.

    lttng now requires kprobes to be enabled, or the following error
    is thrown:

    |
    build/tmp/work/qemux86_64-poky-linux/lttng-modules/2.12.2-r0/lttng-modules-2.12.2/wrapper/kallsyms.c:20:3:
    error: #error "LTTng-modules requires CONFIG_KPROBES on kernels >= 5.7.0"
    |    20 | # error "LTTng-modules requires CONFIG_KPROBES on kernels >= 5.7.0"
    |       |   ^~~~~
    | make[3]: ***
    [build/tmp/work-shared/qemux86-64/kernel-source/scripts/Makefile.build:280:
    build/tmp/work/qemux86_64-poky-linux/lttng-modules/2.12.2-r0/lttng-modules-2.12.2/wrapper/kallsyms.o]
    Error 1

    By including the kprobes fragment into the -rt kernel by default, we
    fix the issue.
