tests: mark python libmount tests known to fail with AddressSanitizer

The tests fail with an error similar to this.

Traceback (most recent call last):
  File "/home/src/util-linux/libmount/python/test_mount_tab_update.py", line 7, in <module>
    import pylibmount as mnt
ImportError: /home/src/util-linux/.libs/libuuid.so.1: undefined symbol: __asan_option_detect_stack_use_after_return

It might be possible to build ASAN-DSO and set LD_PRELOAD, but this
solution is not officially supported.  See the reference for details.
