Skip #39 testcases-cons case for mawk.

Reported by Paul A. Patience.

The test case depends on the order of keys in an associative
array. This is not good, but be that as it may, the test case
works for the Ubuntu 18 version of mawk (32 and 64 bit).
It looks like Mawk has been changing something in its assoc
array implementation, like the hashing function or whatever.
Let's just skip mawk for that test. If it starts breaking for
gawk, we will do a real fix.
