[clang] clang: Use correct triple when constructing offload bundler command (PR #195271)

[Matt Arsenault via cfe-commits]

https://github.com/arsenm created https://github.com/llvm/llvm-project/pull/195271

Use the toolchain triple for the particular input instead of the top
level toolchain. NFC for now, but avoids mismatched triples in
a future change.
