BaseTools: build_rule.template generate a different dll for wholearchive.

When running the /wholearchive test build, generate the test .dll as a
different filename to prevent the system holding onto the dll file too
long and generating a build error that the actual dll cannot be found.
Remove the temporary file after it was generated because the successful
completion of the link command is the test case.
