tools/patchelf: bump to use latest master

Recent ABI_VERSION commits make use of patchelf. It was discovered that
with patchelf 0.10(and even 0.12) various big endian targets fail to
link against libubox SO that was processed through patchelf. Using
latest master patchelf fixes those link errors.

Potential commits affecting big-endian processing
