thin-provisioning-tools: add target and sysroot to bindgen flags

BUILD_CFLAGS doesn't contain information about the recipe sysroot nor about the target
system - and in case these are not specified for bindgen, then it builds against
the build system's headers, using the build system's arch.

Instead of BUILD_CFLAGS pass HOST_CC_ARCH and TOOLCHAIN_OPTIONS, which contain the sysroot
and the requred cross-compiling flags, beside passing the target flag also.

Fixes the following do_compile error:

|   /usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found
|   thread 'main' panicked at /yocto/sandbox/build/tmp/work/cortexa72-poky-linux/thin-provisioning-tools/1.1.0/sources-unpack/cargo_home/bitbake/devicemapper-sys-0.3.0/build.rs:24:10:
|   Could not generate dm.h bindings: ClangDiagnostic("/usr/include/linux/types.h:5:10: fatal error: 'asm/types.h' file not found\n")
