gotools patch committed: Remove test directories in mostlyclean

[Ian Lance Taylor]

This patch fixes the gotools Makefile to remove some more test
directories when running `make mostlyclean`.  It also cleans up the
chmod to avoid an error message when the directory does not exist.
This fixes PR 89193.  Ran gotools tests, ran various make clean
targets on x86_64-pc-linux-gnu.  Committed to mainline.
