Jinghao Jia 8b125949df samples/hid: fix broken vmlinux path for VMLINUX_BTF 
Commit 13b25489b6 ("kbuild: change working directory to external
module directory with M=") changed kbuild working directory of hid-bpf
sample programs to samples/hid, which broke the vmlinux path for
VMLINUX_BTF, as the Makefiles assume the current work directory to be
the kernel output directory and use a relative path (i.e., ./vmlinux):

  Makefile:173: *** Cannot find a vmlinux for VMLINUX_BTF at any of "  /path/to/linux/samples/hid/vmlinux", build the kernel or set VMLINUX_BTF or VMLINUX_H variable.  Stop.

Correctly refer to the kernel output directory using $(objtree).
