[testsuite] Don't use 'testfile' before 'standard_testfile'.

While running tests on arm-none-eabi, I noticed following errors in some
gdb.threads tests.

ERROR: can't read "testfile": no such variable

These were being caused by ${testfile} being used before 'standard_testfile'
which sets it. This patch just moves standard_testfile before the use.
