selftests/bpf: Fix runqslower cross-endian build 
The runqslower binary from a cross-endian build currently fails to run
because the included skeleton has host endianness. Fix this by passing the
target BPF endianness to the runqslower sub-make.

Fixes: 5a63c33 ("selftests/bpf: Support cross-endian building")
