LU-14093 tests: silence gcc10 error for badarea_io

With gcc10 badarea_io will fail to build with the following error.

badarea_io.c: In function ‘main’:
badarea_io.c:59:7: error: ‘write’ reading 2097152 bytes from a
                           region of size 4 [-Werror=stringop-overflow=]
   59 |  rc = write(fd, &fd, 2UL*1024*1024);
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Talking to Oleg see stated this is the done this way on purpose.
So instead of 'fixing' the issue in this case we silence the gcc
warning.
