[Automake-NG] [FYI] [ng] tests: fix test driver botch-up on Solaris

[Stefano Lattarini]

This issue is very similar to the one fixed by commit v1.12.2-31-g587e0c6.

The test 't/memoize.sh' was producing a '.log' file with few overly-long
lines (more than 12k characters long) and, when Solaris XPG4 awk was in
use, that was causing the 'test-driver.sh' script to experience a spurious
failure:

    /usr/xpg4/bin/awk: line 382 (B): Record too long (LIMIT: 19999 bytes)
    tap-driver.sh: fatal: I/O or internal error

* t/memoize.sh: Temporary disable shell tracing and make output in a few
places, to prevent the resulting '.log' file to contain overly long lines.
