    rtla: Fix build without libbpf header

    rtla supports building without libbpf. However, BPF actions
    patchset [1] adds an include of bpf/libbpf.h into timerlat_bpf.h,
    which breaks build on systems that don't have libbpf headers
    installed.

    This is a leftover from a draft version of the patchset where
    timerlat_bpf_set_action() (which takes a struct bpf_program * argument)
    was defined in the header. timerlat_bpf.c already includes bpf/libbpf.h
    via timerlat.skel.h when libbpf is present.

    Remove the redundant include to fix build on systems without libbpf
    headers.
