Commit 5a6ea7022ff4 ("samples/bpf: Remove unnecessary -I flags from
libbpf EXTRA_CFLAGS") fixed the build error caused by redundant include
path for samples/bpf, but not samples/hid.

Apply the same fix on samples/hid as well.

Fixes: 13b25489b6f8 ("kbuild: change working directory to external module directory with M=")
