tests/py: Use libnftables instead of calling nft binary
This adds a simple nftables Python class in py/ which gives access to libnftables API via ctypes module. is extended to make use of the above class instead of calling nft binary. Since command line formatting had to be touched anyway, this patch also streamlines things a bit by introducing __str__ methods to classes Table and Chain and making extensive use of format strings instead of onerously adding all string parts together. Since the called commands don't see a shell anymore, all shell meta character escaping done in testcases is removed. The visible effects of this change are: * Four new warnings in ip/flowtable.t due to changing objref IDs (will be addressed later in a patch to libnftnl). * Reported command line in warning and error messages changed slightly for obvious reasons. * Reduction of a full test run's runtime by a factor of four.
