[PULL 29/30] tests/docker: only enable ubsan for test-clang

[Paolo Bonzini]

-fsanitize=undefined is not the same thing as --enable-sanitizers.  After
commit 47c823e ("tests/docker: add sanitizers back to clang build", 2019-09-11)
test-clang is almost duplicating the asan (test-debug) test, so
partly revert commit 47c823e5b while leaving ubsan enabled.
