libbpf: Remove arch-specific include path in Makefile
Ubuntu mainline builds for ppc64le are failing with the below error (*):
CALL /home/kernel/COD/linux/scripts/atomic/check-atomics.sh
DESCEND bpf/resolve_btfids
Auto-detecting system features:
... libelf: [ [32mon[m ]
... zlib: [ [32mon[m ]
... bpf: [ [31mOFF[m ]
BPF API too old

resolve_btfids needs to be build as a host binary and it needs libbpf.
However, libbpf Makefile hardcodes an include path utilizing $(ARCH).
This results in mixing of cross-architecture headers resulting in a
build failure.
The specific header include path doesn't seem necessary for a libbpf
build. Hence, remove the same.
