Fix GH-10489: run-tests.php does not escape path when building cmd

Multiple tests had to be changed to escape the arguments in shell
commands. Some tests are skipped because they behave differently with
spaces in the path versus without. One notable example of this is the
hashbang test which does not work because spaces in hashbangs paths are
not supported in Linux.
