Tao Su 6bb955fce0 Revert "selftests/harness: remove use of LINE_MAX" ...

Patch series "Selftests: Fix compilation warnings due to missing
_GNU_SOURCE definition", v2.

Since kselftest_harness.h introduces asprintf()[1], many selftests have
compilation warnings or errors due to missing _GNU_SOURCE definitions.

The issue stems from a lack of a LINE_MAX definition in Android (see
commit 38c957f070), which is the reason why asprintf() was introduced. 
We tried adding _GNU_SOURCE definitions to more selftests to fix, but
asprintf() may continue to cause problems, and since it is quite late in
the 6.9 cycle, we would like to revert 8092162335 first to provide
testing for forks[2].

This patch (of 2):

This reverts commit 8092162335.

asprintf() is declared in stdio.h when defining _GNU_SOURCE, but stdio.h
is so common that many files don't define _GNU_SOURCE before including
stdio.h, and defining _GNU_SOURCE after including stdio.h will no longer
take effect, which causes warnings or even errors during compilation in
many selftests.

Revert 'commit 8092162335 ("selftests/harness: remove use of LINE_MAX")'
as that came in quite late in the 6.9 cycle.
