cql-pytest: tests for fromJson() setting a map<ascii, int>

Browse Source 
The fromJson() function can take a map JSON and use it to set a map column.
However, the specific example of a map<ascii, int> doesn't work in Scylla
(it does work in Cassandra). The xfailing tests in this patch demonstrate
this. Although the tests use perfectly legal ASCII, scylla fails the
fromJson() function, with a misleading error.

Refs #7949.
