[gdb/testsuite] Run one more test-case with ASAN_OPTIONS=verify_asan_link_order=0

After building gdb with asan, and running test-case
gdb.trace/basic-libipa.exp, I got:
...
(gdb) run ^M
Starting program: basic-libipa ^M
[Thread debugging using libthread_db enabled]^M
Using host libthread_db library "/lib64/libthread_db.so.1".^M
==7705==ASan runtime does not come first in initial library list; you should \
  either link runtime to your application or manually preload it with \
  LD_PRELOAD.^M
[Inferior 1 (process 7705) exited with code 01]^M
(gdb) FAIL: gdb.trace/basic-libipa.exp: runto: run to main
...

Fix this in the same way as in commit 75948417af8 ("[gdb/testsuite] Run two
test-cases with ASAN_OPTIONS=verify_asan_link_order=0").

Tested on x86_64-linux.
