[GIT PULL] rtla: Fix build failure without libbpf

[Steven Rostedt]

Linus,

rtla fixes for 7.0:

- Fix build failure when libbpf does not exist

  RTLA supports building without BPF libraries, but a recent change
  added a libbpf.h include outside of the BPF protection which caused
  build failures when libbpf was not installed.

    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.
