Fix clear_out() not deleting files in cmdTests

Shell wildcards are not expanded when quoted, and thus the contents of
the temporary output directories were never being cleared.

One of the tests in bootstrapCmdTests had to be fixed as a result, since
it was relying on a TASTy file created by a previous test still existing
in the $OUT directory after having been cleared.
