Not all builds name the compiler executable `clang`. For example, the Fuchsia build bots use `llvm` as their single toolchain executable name, as they combine everything together in a busybot-style binary.

Update the Clang driver test to simply check that a non-empty path is provided for the `--thinlto-remote-compiler` argument, rather than hardcoding the executable name. The cross-project test will verify that the path is valid later.

Should fix #<!-- -->147265.
