thin-provisioning-tools: fix bindgen build error with clang on octeontx2

Remove unsupported '-mcpu=octeontx2+crypto' from BINDGEN_EXTRA_CLANG_ARGS
as clang does not recognize 'octeontx2' as a valid target CPU, causing
bindgen to fail when generating Rust bindings.

Since bindgen only parses headers using Clang, CPU-specific options
like -mcpu are generally unnecessary.

Fixes build failure:
|   error: unsupported argument 'octeontx2+crypto' to option '-mcpu='
|   error: unknown target CPU 'octeontx2'
