[C++] arrow-compute-asof-join-node-test inordinately slow

[asfimport]

It seems that arrow-compute-asof-join-node-test is designed such as each sub-test takes 2 seconds. The entire test file takes 120 seconds here.

This is much too slow for a single test file and should drastically be reduced.

@rtpsw Could you take a look and try to improve things here?

IIRC, at the time, I asked about the timeout for this test, and the answer was something like 300 seconds. How much do we want it to be? I can set  it rather flexibly.

Antoine Pitrou / @pitrou:
300 seconds might be the timeout set on CI in case a test is stuck, but a test file shouldn't certainly not come near that duration.

10 seconds max would be a reasonable target IMHO.

Yaron Gvili / @rtpsw:
Note that I'll set the timeout at the test-case level, not for the entire test executable. I'll cut it down by a factor of 10.
