gh-103053: Fix test_tools.test_freeze on FreeBSD (#110451)

Fix test_tools.test_freeze on FreeBSD: run "make distclean" instead
of "make clean" in the copied source directory to remove also the
"python" program.

Other test_freeze changes:

* Log executed commands and directories, and the current directory.
* No longer uses make -C option to change the directory, instead use
  subprocess cwd parameter.
