gollvm: resolve arg[0] path in -v/-### trace output
The go command takes advantage of the -### compiler output to
derive the path to the compiler executable, as part of computing
a checksum / buildid for the compilation. To help with this,
make sure that the -v / -### output emits a resolved executable
path and not just the argv[0] value.
