Summary:
crash tests donot run in DEBUG_MODE=0 on tmpfs when
use_direct_reads/use_direct_io_for_flush_and_compaction is set randomly because
direct I/O is not supported on tmpfs and tests exit.
Fix: Sanitize direct I/O read options in DEBUG_LEVEL=0 so that crash
tests can run in tmpfs. When mmap_reads is set, direct I/O reads options are
unset so we can sanitize direct I/O reads options in case of tmpfs as well.

Test Plan:
1. export DEBUG_LEVEL=0; export TEST_TMPDIR="/dev/shm";
export CRASH_TEST_EXT_ARGS="--use_direct_reads=1 --mmap_read=0";
make crash_test -j64
2. In DEBUG_LEVEL=1 mode: make crash_test -j64
